DEAR ABBY: My son, "Peter," is in college working on a postgraduate degree. He arranged a date with a young woman while they were home over the holidays. After accepting the first date and breaking it, she agreed to a second one. As Peter was driving to pick her up, he called to double-check her address only to be told she was still at a previous engagement. Naturally, Peter expected she'd call back when she was free -- but she didn't. There was no explanation, no call or text or any further communication.

What is happening to young people today? Do texting and online social networking encourage them to avoid simple human kindness and consideration of others? I think these new devices are giving kids an easy way to get out of difficult and uncomfortable situations. They don't have to hear the hurt of rejection or the sting of their rudeness through a text or a chat page.

Meanwhile, my thoughtful, sensitive son sat home thinking he wasn't important enough for an explanation! At 26 he's beginning to think he should just focus on finishing school and forget the dating scene. And if this is the caliber of today's young women, maybe he should! -- MOTHER OF A GOOD SON

DEAR MOTHER: Your son may be thoughtful and sensitive, but he appears to have unfortunate taste in women. You say he is working on a postgraduate degree? How old was the girl -- because she appears to have the emotional maturity of a young teenager. Nobody likes rejection, but Peter should consider the source. Rather than giving up on dating, he should look for company among women who are at his intellectual and emotional level -- in college or grad school or perhaps a little older.

DEAR ABBY: I am a 29-year-old female who would like to know why people feel compelled to tell random strangers to "smile."

I was in the market the other night and a man came walking by me saying, "You dropped something," and was pointing to the floor. I looked down and said, "I don't see anything." He then told me, "You dropped your smile."

Abby, I was SO not amused. I turned around going back to my business saying, "Oh, OK." The man proceeded to walk away mumbling, "Don't look so serious. It's only the grocery store."

I hate when people do this. It happens to me a lot and has most of my life. People -- especially seniors -- say, "Don't you dare smile for me, don't you dare!" Or, "Smile! You're too cute not to smile." An old gentleman said, "Oh, she's like ice -- so cold, never smiles."

What can I do if this happens again? I don't see the need to walk around the store or sit at my desk at work with a Cheshire cat grin on my face all day. Any suggestions? -- OFFENDED IN GILROY, CALIF.

DEAR OFFENDED: The man who asked if you had "lost" something may have been making a clumsy attempt to pick you up. That sometimes happens in markets. As to the "older people" who comment on your expression -- or lack thereof -- they may consider themselves so "senior" that they can "coax" you into doing as they would like -- like "coochy-kooing" a baby to make it laugh on cue.

Making personal remarks to strangers is, of course, rude. My advice to you is to distance yourself from those individuals as quickly as possible. Speaking personally, if I was approached the way you have been, the last thing I'd be inclined to do is smile or engage them at all. I'd be offended, too.

DEAR ABBY: I'm 16 and have grown up religious my whole life. I get good grades and stay out of trouble. A lot of my friends have done crazy things like drinking and partying, but I haven't. Because of this, I have the reputation of being a "goody-two-shoes."

I'm not saying it's a bad thing being a good girl, but I don't want to be a goody-two-shoes. Part of me wants to try some of the stuff my friends have been doing, but I don't want to lose my parents' trust. Please help! -- RESTLESS IN OREGON

DEAR RESTLESS: You have your parents' trust because you have earned it. Before you try any of the "stuff" your friends have been doing, ask yourself what the consequences could be. Yes, it's hard being labeled a goody-two-shoes -- but please look closely at who is doing the name-calling. A streetwise individual once told me, "The best way out of a jam is not to get into one in the first place." That tidbit has served me well, and that's why I'm passing it along to you.

DEAR ABBY: My daughter left our small Midwestern town for the West Coast to marry money. At 37, she finally snagged her millionaire. She thought it was going to give her a blank check.

She does live in a lovely home and drives an expensive foreign car, but that's where it ends. Everything is in his name, and her wedding ring is one we gave her, although he paid to remove the stone and have it polished. I told her then to walk away.

They have two children. Her son is a spoiled brat, completely self-absorbed like his dad. Her daughter has learning disabilities and is still at home.

More than one family member refers to her spouse as a horse's rear end. He rarely attends family events, which is really fine with everyone. At best, he can be described as rude and obnoxious.

My daughter would never leave him. She loves the lifestyle too much. If she only knew how most of her extended family think of them. I'm embarrassed by it, really.

I just thought your readers should know that marrying money isn't necessarily the pot of gold at the end of the rainbow. -- HER MOM IN WISCONSIN

DEAR MOM: I'll say. Someone who marries for money usually ends up earning every single penny.

DEAR ABBY: My husband was recently invited to the wedding of one of his co-workers. The wedding is in Mexico. Shouldn't these types of invitations be issued to family and very close friends only? I can't help but feel she is just looking for a gift. Is this proper, or am I "seeing" the bigger picture? -- ANNOYED IN ILLINOIS

DEAR ANNOYED: No, and there are a few things wrong with this "picture." If the co-worker knows your husband is married, the invitation should have properly been addressed to "Mr. and Mrs." Since it wasn't, and I assume your husband has no intention of attending, he should send his regrets.

However, because the bride is someone he will be interacting with on an ongoing basis, the politic way to handle this would be to present the happy couple with a token gift from both of you upon their return -- although you are not socially obligated to do so.

DEAR ABBY: I am a medic in the Middle East. I was out on patrol with some of our guys when we were hit with a mortar attack. More than one guy was wounded.

I ran to the first guy and saw that he was hit. He had a wound I knew he wouldn't be able to survive. He pulled a letter from his pocket, put it in my hands and pushed me away. I tried to apply pressure to his wound to slow the bleeding, but he pushed me away again. It was like he was telling me to go to the next man who needed my attention. Everyone survived except him.

At first, I thought I did the right thing by respecting his wishes to help someone I could save. When I got back and talked to his family, they were angry at me for not trying harder to save his life. When I signed up for this job, I knew I wouldn't be able to save everyone, but I am supposed to try my best no matter who it is I am saving.

Was I wrong by going to another man who I could save? Was it wrong of me to take his letter and leave him after he pushed me away twice? Please tell me what you think. -- DOC IN DISTRESS

DEAR DOC: I think you were doing the best you could in an impossible situation. Your patient may have instinctively known he was not going to make it -- which is why he gave you the letter. Of course the family was angry that you couldn't save their loved one -- they are grieving. I urge you to talk to a counselor about what happened and the feelings of guilt you're experiencing. In a situation like the one in which you found yourself, wrenching choices sometimes have to be made. Please stop second-guessing yourself.

DEAR ABBY: My father is in the early stages of Alzheimer's. While at a family party, my stepmother started talking about how she and Dad had just visited their friends, the Royal Family in England. I assume she thought she was being funny. My poor father was completely confused, but my stepmother continued on with the charade. We all felt uncomfortable and didn't know how to handle the situation. The grandkids felt bad for Grandpop.

I recently learned that my stepmother pretended her friend was his daughter. Dad is confused enough without having to be tricked in this manner. My stepmother is a very complex, challenging woman, and I need to handle this matter very carefully. Any suggestions would be greatly appreciated. -- SAD ABOUT DAD IN NEW JERSEY

DEAR SAD: Your stepmother is not only "complex and challenging," she has a twisted sense of humor. Ridiculing someone with dementia is cruel and, in my opinion, qualifies as elder abuse. As to "tricking" your father into thinking her friend was his daughter, I wish you had mentioned what she was trying to accomplish by doing that. Your father -- and his assets -- may need protection. Please consider discussing this with a social worker who specializes in senior services.

DEAR ABBY: My husband doesn't like his sister. When he drinks beer, he says ugly things about her and starts to cry. When I said she's his only sister and to cut it out, he closed his hands into fists.

I twice tried calling her at 1 a.m., after he fell asleep. Well, our phone bill arrived and her phone number is on it. He's the one who gets the mail, so please answer this in the paper. The bill is due in 10 days. -- PEACEMAKER IN FLORIDA

DEAR PEACEMAKER: If your husband is the one who pays the bills, fess up while he's sober, because it appears he doesn't handle his beer very well. And from now on, respect his boundaries because there may be good reason why he and his sister are on the outs.
