DEAR ABBY: I am 15, and have never been very close to my parents. In fact, I haven't lived with them since I was a baby -- they were too young to raise me. They've always been "around," but they feel more like an aunt and uncle than my parents.

They are both going through a rough time. My father is going through a divorce, and my mother just found out that she has cancer. I don't know what to say to them. I love them both. The thing that scares me the most is that it doesn't faze me about the cancer. What is wrong with me? -- DISCONNECTED IN ARKANSAS

DEAR DISCONNECTED: There is nothing "wrong" with you. When someone close is diagnosed with a possible life-threatening illness, denial is a common reaction.

As to what to say to your parents during this difficult time -- no fancy speeches are necessary. No one expects you to solve the problems or make the pain go away. Just tell your parents you love them. That's all they need to hear.

DEAR ABBY: I have some dear friends whose daughter was married last March. The wedding, which I attended, was held in their home state. I also sent a very nice gift.

I have never received a thank-you note from this young woman, and I know of at least one other person who hasn't either. Should I just forget it -- or is it permissible to bring this subject up with her parents, my dear friends? It's possible they do not know how absolutely awful their daughter's manners are. We have been friends for more than 25 years. -- FUMING IN RIDGEFIELD, N.J.

DEAR FUMING: Everyone would be better served if you discussed this with the young woman instead of tattling to her parents. I see nothing to be gained by embarrassing and upsetting them. If they are the kind of people who have been dear friends of yours for 25 years, they certainly are familiar with the social graces. It's a pity they didn't rub off on their daughter.

DEAR ABBY: I am a professional truck driver. The recent letter from "A Fitness Cyclist for 40 Years" inspired me to explain to the public why truck drivers do certain things on the road.

We change from one lane to another to avoid a vehicle that has broken down, a police officer stopped on the side of the road or a cyclist. People do not realize the draft from a large truck could pull a cyclist toward the trailer and under the wheels. Please, drivers, do not try to pass us on the right when we change lanes. Wait until we return to our lane.

Also, when it's raining, please turn your headlights on so we can see you. And please don't race to get ahead of us at an off-ramp.

People may not like trucks on the road, Abby, but remember -- the only thing not delivered by a truck is a baby! -- MIKE MILBURN, PORT CHARLOTTE, FLA.

DEAR MIKE: Thank you for your important tips. Trucks are vital pipelines in our healthy economy. I have received many letters from readers wanting to thank truck drivers for their assistance in road emergencies. Truck drivers are some of the most courteous and safest drivers on our highways. Keep up the good work.

DEAR ABBY: Last fall, my live-in boyfriend was abusive to me. My parents chipped right in and helped me move back to my hometown. They were wonderful and supportive even though I'd let them down in the past. They even bought a house so my children and I would have somewhere to live.

This boyfriend went to classes, did a lot of praying and I believe he's actually changed. I really do! Abby, he's the father of one of my children. We've started seeing each other and it really feels right. We want to get married.

My mother refuses to accept that he could have changed, and makes it clear she doesn't approve. She says if I get back together with him, they will have wasted all that time and money they invested in bailing me out. She says it's my low self-esteem that makes me want to see him.

I don't know how to resolve this. I'm in my late 30s yet I still want my parents' approval. Please help. -- DAUGHTER OF AN IRON-WILLED IOWA MOM

DEAR DAUGHTER: Your mother knows you better than I do. She loves you and doesn't want to see you hurt again, and I can't fault her for that.

Daughter, I'm extremely skeptical about your chances of success in this relationship. If you decide to pursue it, I wish you the best of luck because I'm convinced you're going to need it.

A small percentage of abusers -- those who are truly determined and self-motivated -- can change if they receive long-term counseling. Only time (at least another year of counseling) will tell if this leopard has been able to change his spots.

Under no circumstances should you reconcile with him unless you maintain financial independence. That way, if he should backslide, you won't have to depend on anyone to bail you out. Should you decide to marry this "prize" I urge you to have a rock-solid prenuptial agreement so that you will be taken care of.

So your parents feel they have not "wasted" the money they invested in trying to help you, sell or rent the house and give the proceeds to them.

DEAR ABBY: I quit my job last year to stay at home with my children. All of a sudden, friends and neighbors began calling me to run errands, watch their children, sew costumes for the school plays, etc. Nobody seemed to understand that being a mother IS a full-time job.

Finally, I found a way to stop all the requests for favors: I made up fliers advertising myself as a "domestic consultant." I offered to baby-sit, pick up dry cleaning and groceries, sew and do other odd jobs for a negotiable fee.

The calls are much less frequent now. When someone does call, he or she is prepared to pay me fairly for child care and errand running. When I get requests for things that would interfere with plans I've made with my children (or don't want to do!), I simply tell the caller, "I am overbooked." -- ALREADY WORKING (THANK YOU VERY MUCH)

DEAR ALREADY WORKING (TYVM): You're a clever woman and you may have devised a method from which other stay-at-home parents can benefit.

DEAR ABBY: A good friend of mine was married recently, without a traditional reception. I have now been invited to a postnuptial reception for the couple. Does a postnuptial reception carry an obligation to send a gift? -- BOB IN OHIO

DEAR BOB: Yes, it does. If you attend the reception, a token of your good wishes is in order.

DEAR ABBY: I am 50 and have been divorced for two years after a 29-year marriage that was, at times, physically and emotionally abusive. I work full-time and attend college full-time.

Two loving and caring friends have helped me through the bad times with encouragement and advice. I often heed their advice, since most of the time it has been good and held true. However, I recently made a decision that has caused a rift between us and this disturbs me.

My son (age 30) and my daughter-in-law (24) have invited me to live with them until I complete my schooling, and I have accepted their invitation. This eases my financial burden (tuition, books, bills, life) greatly. They both have good jobs, no children yet, and are solid and easygoing. My girlfriends are appalled that I could live with my children who have been married only two years! They feel I would be invading their privacy and giving up mine, along with my independence. I assured them that this is only a temporary arrangement, since I have only a year and a half to finish school. I told them the most important factor is that it is OK with my children and OK with me.

My kids and I have discussed privacy issues and personal issues, and we all feel very comfortable with this. One of my friends said she wouldn't visit me at their home because she would "feel uncomfortable." My other friend told me she just doesn't feel that this is right. I love my friends dearly, but I am getting that eerie feeling of "control" from them that I had in my marriage. Am I right, or just paranoid? I'm afraid of making the wrong decision.

My children and I really do feel comfortable with the whole thing. Should I tell my friends it's time to "let me go" and lead my own life now? My friends also disagree with the friendship my ex-husband, his wife and I have. My ex and I both sought counseling during and after our divorce which uncovered a lot of hurt and allowed a lot of healing for both of us.

Help! These two are driving me crazy! -- JANE IN YAKIMA, WASH.

DEAR JANE: You appear to have your life on track after many unhappy years. Your friends may be well-meaning, but threatening not to visit as long as you live with your son and his wife is blackmail. Don't submit to it. Your relationships with your son, his wife and your former husband are admirable. Unless your friends are willing to stop dictating how you should live your life, now may be the time to start broadening your circle of friends.

DEAR ABBY: I dated "Howard" for eight months. He gave me a beautiful diamond tennis bracelet for my birthday. I broke up with him a month later. Now he's asking for the bracelet back! I don't want to return it. Do you think I have to? -- DIAMONDS ARE NOT FOREVER?

DEAR DIAMONDS: A diamond bracelet is a very expensive gift. Since you had it only a month before breaking up with Howard, the honorable thing would be to return it. Perhaps he'll be lucky enough to find another young woman who'll realize that as precious as the bracelet may be, he's the real "jewel."
