DEAR ABBY: I am 18 years old and would like to know what kinds of symptoms show that it's time for counseling -- depression, mood swings, etc. -- CONSIDERING IT IN OHIO

DEAR CONSIDERING IT: You have asked an important question. Everybody experiences sadness at some point, but sadness that doesn't go away can actually be depression, a medical condition. Anyone, regardless of age, who experiences any five of the following symptoms for two weeks or more should discuss it with a mental health professional:

1. Feeling of sadness and/or irritability.

2. Loss of interest or pleasure in activities once enjoyed.

3. Changes in weight and appetite.

4. Changes in sleep patterns.

5. Feeling guilty, hopeless or worthless.

6. Inability to concentrate, remember things or make decisions.

7. Restlessness or decreased activity noticed by others.

8. Fatigue or loss of energy.

9. Thoughts of death or suicide.

DEAR ABBY: I have a wonderful hairdresser who helps not only me but also many of my friends and family members. She's the sole support for her family and the sweetest person you could ever meet. The issue is her sense of time.

There's no problem if you're the first or second appointment of the day, but after that she runs further and further behind. Yesterday, it took my frail mother-in-law 3 1/2 hours to get her hair done because of the wait time. I was the first appointment at 7:30 a.m. and she didn't make it into the shop until 7:40. How can I help her understand she's driving her customers away without offending her? -- CUTTING TIME IN UTAH

DEAR CUTTING TIME: Your hairdresser may be good at styling hair but it appears she's not a very good businesswoman. If she's losing customers because she manages her schedule so poorly, tell her why. You will be doing her a favor. And please, before you bring your frail mother-in-law in for another appointment, call to find out how late the woman is running before letting your mother-in-law sit for 3 1/2 hours before even seeing a shampoo bowl.

DEAR ABBY: I recently bought a small travel trailer that I use for weekend fishing trips. My dog, "Goldie," accompanies me on these short trips and sleeps with me on the only bed in the trailer.

My wife, "Shirley," is now expecting to go on some of my fishing trips with Goldie and me. The problem is, Goldie is used to sleeping with me, and I believe she should have first dibs on the bed since she was there first.

When I informed Shirley that she'd be sleeping in the back of the truck, she came unglued. Now, Shirley and I are hardly speaking. Goldie is a young Lab pup who is my very best friend, constant companion and never nags. I think my wife is being selfish and inconsiderate, but I'd like your opinion. Am I out of line here? -- GOIN' FISHIN' IN MIDLAND, TEXAS

DEAR GOIN' FISHIN': If you're expecting sympathy from me, you're barking up the wrong tree. You are not only out of line, but it appears you're also in the doghouse. A real Texas gentleman would let Shirley and Goldie share the bed while he slept in the truck, and that's what I'm urging you to do.

DEAR ABBY: I go to movies occasionally with my niece "Connie" and her two kids. Although the theater has a sign "No Outside Food or Drinks Allowed," Connie sneaks snacks in in her oversized purse, then doles them out after the lights go down. I'm not talking about a couple of candy bars; she brings bags of candy, chips and cans of soda.

While I agree with my niece that the price of refreshments is outrageous, I also believe it's the theater operators' prerogative to set prices and policy. I suggested Connie skip the snacks during the movie and take the kids out for ice cream afterward, but she said she didn't want to "deprive" them. When I offered to pay, she said it wasn't about the money, it was "the principle, and besides, "everybody else does it."

I feel my niece is teaching her kids it's OK to break rules you find inconvenient as long as you can get away with it. I enjoy the outings with them so I've dropped the subject for the sake of harmony, but it still bothers me. Connie probably thinks I'm a critical old crank who's out of step with the times. I'd love your opinion. -- PAYING FOR MY POPCORN IN OREGON

DEAR PAYING: Here it is: Your thinking is spot on. Your niece's behavior is dishonest, and children model their behavior on the example set by their parents. Connie's excuse that everybody does it is a cop-out. Because "everyone" does something doesn't make it right.

Theater owners earn a large portion of their profits not from ticket sales, but from their concession stands. I am often struck by the amount of food I see purchased before people enter a theater -- large tubs of popcorn, king-sized candy bars, bucket-sized soft drinks and nachos. What does this say about us?

Obesity is at record levels in the U.S. We are repeatedly cautioned not to eat in front of the television set. The munching going on in theaters is another example of mindless, compulsive eating.

If Connie doesn't want to "deprive" her children, she should feed them a healthy meal before they go to the movie so they won't be hungry. That's my opinion, so I'm glad you asked me.

DEAR ABBY: After six years of marriage I am seven months pregnant. I never wanted children and did not expect this to happen. I am determined to be an excellent mother, but it's an intellectual exercise for me. I feel nothing for this baby and I have a hard time imagining our future. I also hate being pregnant.

I can't find any websites for women like me -- they're filled with women cooing over their bellies and fantasizing over their babies-to-be. I mentioned my feelings (or lack thereof) to my husband and he became furious with me. Is there something wrong with me? -- LACKS THE MOTHERING GENE

DEAR LACKS: No, there's nothing "wrong" with you. You're just not particularly maternal. I'm sure many women have felt as you do because more than half the pregnancies in the U.S. are "unplanned."

Discuss this with your obstetrician to be sure you're not suffering from pre-partum depression. When your baby arrives I am sure that you will fall in love with him or her as many other mothers have. Your husband may have reacted the way he did because he felt it was in some way a rejection of him, or because he does want children.

DEAR ABBY: My wife and I have been married for 10 years, and it is a wonderful marriage. We love each other very much, never argue and get along great. We have a 2-year-old child.

Recently I found a "sex tape" online of my wife with the guy she dated before me. This video was taken without her knowledge and is from 13 years ago. Because of this, I am not upset about it.

My question is, should I bring this to her attention, and if so, how? I feel she needs to know it's out there. I'm reacting to this as a man would. I don't know how a woman would react. Please help. -- IT'S PRIVATE

DEAR IT'S PRIVATE: Although there are no sex tapes of me floating around, I can tell you from a woman's perspective that if there was one (and the lighting was unflattering), I'd be furious. Your wife has a right to know, so don't keep her in the dark.

P.S. How did you come across that video? I'm sure she will be interested to know.

DEAR ABBY: A couple of years ago, my husband of 30 years became distant. He didn't want to touch me, talk to me or spend time with me. I was devastated.

An old boyfriend emailed me to offer condolences on the death of my brother. There were just chatty emails at the beginning, about our lives and how we had gone such separate ways in 40 years. The emails started becoming more intimate, as I was fed by his seeming "love" for me. He told me I was his "soul mate" and I fell for it. I took risks to see him, eventually slept with him and lied to everyone I know in the process.

Recently my husband came across an email from the past boyfriend. My secret was out and the truth was ugly. I had betrayed God, my husband, my mother and my four beautiful children. My husband no longer trusts me and wants a divorce.

Abby, please tell your readers to think long and hard before acting out of loneliness. It doesn't just affect the husband and wife; it also has an impact on the entire family, circle of friends and standing within the community. -- ADULTEROUS WIFE IN FLORIDA

DEAR WIFE: How sad that you didn't get to the bottom of your husband's distancing before it led to you having an affair. But before you allow your husband to place all the blame on your shoulders, you should make it your business to learn the reason for HIS behavior -- since "everything" is now out in the open.

DEAR ABBY: I love my husband and, for the most part, we get along great. My only complaint is he stays neutral when someone hurts my feelings.

The latest incident involved good friends of ours until the wife hurt me for the last time. She has a history of inviting me out, even talking me into changing my plans, then ditching me if something better comes along. This last time, I was invited to her house, only to learn (as I'm walking out the door) that she had left for the evening. I've had enough! I gave her as many chances as I did only because my husband said I "overreact" and shouldn't let it be a big deal.

This isn't the first time he has chosen not to validate my feelings. The fact that my husband is never on my side hurts me more than what my "friend" has ever done. Am I right? -- GETS NO SUPPORT IN AZUSA, CALIF.

DEAR GETS NO SUPPORT: Your husband may not want to be caught in the middle of a disagreement between two women, but that's no reason for him not to tell you your feelings are appropriate when they are justified. He may be good friends with the husband, but the wife has shown she's not much of a friend to you. Real friends don't stand each other up if something "better" comes along. Her behavior is rude and insensitive, and I don't blame you for being offended.
