DEAR ABBY: I will graduate soon with a degree in nursing. This is a dream that is finally coming true. The problem is my mother-in-law expects me to take care of her and my father-in-law. They both have health issues, but nothing that requires 24-hour nursing care, and their medical issues can be resolved by simply taking their medications and following their doctors' advice.

I offered to help pay for home health care, but she said she doesn't want "outside" help. She expects me to uproot my family, move in with them and provide round-the-clock care, free of charge. I have worked hard to take care of my husband and children. I can't make a living working for free. I don't know how to say no without causing a major rift in the family. My mother-in-law doesn't take rejection well. Please help me. -- FEELING TRAPPED IN ARIZONA

DEAR FEELING TRAPPED: One of the hardest words in the English language for some people to say is "no." But if you don't master the art of standing up for yourself in a "charming" way, you will spend the rest of your in-laws' lives in indentured servitude.

So tell your mother-in-law that you have worked hard to get your nursing degree, and now you will be starting a career in the field. Tell her that you will gladly "oversee" their care -- from a distance -- but that you are not uprooting the family and moving in with them because it would be too disruptive. This is not "rejection." It is sanity. And it goes without saying your husband should back you up.

DEAR ABBY: My oldest granddaughter, "Allie," is a psychiatrist. I have always loved her, been proud of her accomplishments and have had a warm relationship with her.

Her mother -- my daughter -- got drunk and made several angry, harsh phone calls to Allie. Since then, Allie has refused contact with everyone in the family. I have written to her numerous times and so has my daughter, begging for forgiveness. My daughter has quit drinking, thanks to the patience and loving support of my family. She has also come out of an abusive marriage.

Allie gave birth to a baby girl last year. I have never seen my great-grandchild and it breaks my heart. Abby, what can I do to restore a good relationship with my granddaughter? I love her and pray for her every day. -- GRIEVING GRANDMA

DEAR GRIEVING GRANDMA: As your letter proves, being a mental health professional does not exempt someone from having family problems. Depending upon what your daughter said to Allie, it is understandable that she might want to protect herself -- and her baby -- from her verbally abusive, alcoholic parent. While it may be harsh for Allie to have cut off contact with all of her maternal relatives, including you, she may have done so to prevent you from trying to pressure her to "forgive" her mother for what has been an ongoing pattern of behavior.

Write Allie one more letter advising her that her mother is no longer drinking and has left her abusive marriage. Continue loving and praying for her. But until your granddaughter decides on her own to relent, there is nothing you can do to "fix" this. I'm sorry.

DEAR ABBY: I'm 25 and live in my mother's basement apartment with my boyfriend. We would like to be married soon, now that we're out of school and have stable careers. But I insist that we move out of Mom's house before making any permanent plans.

The problem is my mom, who is divorced, is unemployed and a social phobic, with few friends. We provide her with financial support by paying several hundred dollars a month in rent, in addition to other bills. She helps me with a loan when the rare emergency arises.

Every time I mention moving out, she becomes angry with me. She cries that she'll be left alone with no money -- and it makes me feel so guilty I relent. I have no idea what to do. My older sister, who is married with two children, might be able to help me out, but we have never been close and I'm reluctant to ask for her advice. Please help, Abby. -- MAMA'S GIRL IN ROSWELL, GA.

DEAR MAMA'S GIRL: You are not the solution to your mother's problems. The time has come for you to spread your wings and fly the nest. Before you leave, be sure the apartment is in the freshest condition possible so it can be rented and your mother will have some income. She will probably need professional help to overcome her ingrained social insecurities -- so encourage her to get it. (Some licensed psychotherapists specialize in phobic disorders.) It will change her life -- and yours -- for the better.

DEAR ABBY: If a girl ever needed advice, it's me. My father walked out 20 years ago, leaving four children and a disabled wife. He just vanished. We grew up and I searched for him. Because of the power of the Internet, I was contacted by his family, and Dad was found. He had reunited with his sister, who updated me.

Now I'm faced with the dilemma of how to speak to him for the first time since I was in diapers, and I am angry. My aunt advises me not to ask for answers to questions like "why" because I may not get them. Of the things he did say to her, not once did he express remorse.

I guess what I'm asking is how to talk to this stranger who altered my life. Most of what I have are questions. How am I not entitled to answers? Abby, this has been a long search and now that I have succeeded, I don't know what to do. -- STRESSED IN TEXAS

DEAR STRESSED: Your anger is justified. Unless he was locked in a mental ward, a man who would leave a disabled wife and four small children and "just vanish" is someone with no concern for anyone other than himself. Approach him with the same caution you would any other stranger, because that's what he is. Because this is stressful, list your questions in advance so you won't forget any. But I'm warning you: Do not allow him to make you feel sorry for him.

DEAR ABBY: Last night while walking my dog I noticed the lights in my neighbor's car had been left on. It was after midnight and his house was dark. I am not particularly close to this neighbor, although we acknowledge each other in passing. I rang his doorbell, but he didn't answer. The next morning as I left for work I saw the lights in his car were still on.

What is appropriate in this situation, Abby? Would people want to be told, or is it better to let them sleep? -- CARING NEIGHBOR, BOULDER, COLO.

DEAR NEIGHBOR: I can't speak for everyone, but I know I would much prefer to have someone ring my bell and tell me I forgot to turn off the lights than have to deal with a dead battery in the morning.

DEAR ABBY: My mother has a long history of lying in what appears to be her attempt to manipulate others. She is now 75, and my siblings and I know not to accept anything she says as the truth, and to always check with each other in order to find out the whole story.

The other day she lied to me about a doctor's appointment. Shortly after I talked to her, my sister called me, furious about what Mom had really done. I called Mom back that evening to give her a chance to tell the truth. Instead, she made up another lie to cover up what she had done. That's when I told her I had already spoken to my sister.

The whole situation makes me very sad, which I told her. I let her know I am "on to her" and have decided to give both of us some time to think about the situation. I know you can't teach an old dog new tricks, and I have given up trying.

I love Mom, but her continued manipulation of others has driven me away from her. Is there any way for her to see how much her inappropriate behavior affects those of us who care about her? -- SAD SON IN AUSTIN, TEXAS

DEAR SAD SON: No. And by cross-checking whatever your mother tells you with your siblings, you are handling a difficult situation as well as you can.

DEAR ABBY: Our 19-year-old son is home from college for the summer and he "knows everything." His father and I have told him to wash all fruits and vegetables we buy fresh from the market before eating them. He feels this is not important and continues to eat apples, strawberries and lettuce directly from the container or plastic bag without rinsing them.

Please let me know if our fears are real. I have always been told washing is necessary. I would love to show him something on this subject because he thinks I'm silly and overprotective. -- MOTHER KNOWS BEST IN TEXAS

DEAR M.K.B.: If seeing it in print will get your son's attention, I'm happy to oblige. Have him try this experiment: The next time he decides to eat a nice, shiny apple, have him soak it for 5 to 10 minutes in water to which several tablespoons of vinegar have been added. This will remove the waxy coating that is usually sprayed on them, and with it any dirt or "little critters" that may have become attached.

Also, periodically on the nightly news we hear announcements of FDA recalls because of salmonella or E. coli that has been discovered on various vegetables. Although some are packaged as ready-to-eat, they, too, should be rinsed before using. Consider it "health insurance."

DEAR ABBY: I am the parent of a child with special needs. To an outsider he looks different; adults and children stare at him when we're out.

My son is not aware of their impolite behavior, but I am -- and it really irks me. What should I say to these insensitive people? -- BOILING MAD IN NEW JERSEY

DEAR BOILING MAD: I don't think you should say anything. It is not unusual for individuals of every age to do a double take when they see someone -- or something -- that is "different." Of course staring is impolite, but unless someone makes a remark or asks a question about your son, you should ignore the person.
