DEAR ABBY: I live at a camp in the north woods of Wisconsin. A staff member's kids spend the day at our camp. The kids are annoying, nasty and whiny.

One 8-year-old girl has attached herself to my 7-year-old sister and is pulling her away from our family. She comes up to our house whether or not my sister invites her, and usually makes a mess. She also invites my sister to stay down at the lodge late at night, which makes my sister tired and crabby.

Her 11-year-old brother attaches himself to my 5-year-old brother, and then pushes him around.

I miss spending time with my sister, and I don't like her change in behavior. I have tried to do something about it, but to no avail. If I go out and tell them, they might hate me. What should I do? -- TICKED OFF IN WISCONSIN

DEAR TICKED OFF: Talk to your parents. How do they feel about this? Eleven-year-old boys are too old to play with 5-year-olds. And when the older child pushes the younger one around, it is considered bullying, which should not be tolerated. It's up to your parents to put a stop to it. As to your sister's friendship with the girl, if the time they spend together and the "messes" she creates don't seem to bother your parents, then I guess it's permissible.

Because you miss spending time with your sister, you need to fill it with something else. Camp activities or making friends with some of the other campers your age would be fun, and make you less dependent upon her for company. Please consider it.

DEAR ABBY: My husband's stepsister, "Melanie," visits us from Alabama for five days every year. When Melanie stays with us, she expects to make us a "Southern dinner" one night during her stay. Before she arrived, I told my husband, "Lawton," that I didn't want her making dinner because she goes through my kitchen drawers and cabinets without asking where anything is. She just takes over my kitchen!

I don't mind if Melanie helps herself to something in the refrigerator, gets a plate and silverware or something of that nature. But for her to come in and take over my kitchen and root through every drawer and cabinet truly upsets me.

Lawton went against my wishes and told Melanie it was OK to make the dinner. Abby, I couldn't even stand to be in my own kitchen while she was preparing it. I felt I couldn't say one word in my own home.

Lawton accused me of being "hostile" to her and a spoiled brat. He also let me know it is his home, too, and when his stepsister comes to visit, she's allowed to do whatever she wants.

Am I wrong in feeling the way I do? If I am a guest in someone's home (even my sister's), I never do anything without asking. I was brought up to respect another person's home. I feel my husband should have complied with my wishes. Am I wrong? Please enlighten me. -- UPSET WIFE, POTTSTOWN, PA.

DEAR UPSET WIFE: Your feelings are understandable, and many people -- of both sexes -- feel as you do about their kitchens. However, since "preparing a Southern dinner" has become traditional when Melanie visits, my advice is to ask her what equipment she will need before she starts the preparation, so you can have it sitting on the counter ready for her. That will minimize the amount of "rooting" she has to do, and you will feel less invaded. Bon appetit, y'all!

DEAR ABBY: This is a bit complicated. I was trying to help my sister, "Bree," last year while she was separated from her husband. (I was like a mediator.) I was her maid of honor when they were married years ago. We were close.

Bree is now accusing me of telling her ex about a man she was seeing while they were separated. I did not! She also claims I tried to sleep with her husband. I didn't do that either, Abby. He's not even my type.

She keeps fabricating lies to hurt me, and I keep rebutting them. I feel our relationship is irreparably damaged. Our parents want us to fix this. I really want to mend the rift, but I won't tolerate any more abuse from her. I have done nothing malicious. I almost hate her.

Bree and I live too far apart for counseling. Her young children will be visiting me in a couple of weeks. I love them very much. Do you think I have a chance of fixing our relationship when the kids come? I don't want to put any stress on them. They've been through enough. -- TWISTED SISTERS IN FLORIDA

DEAR SISTER: It would be interesting to know who filled your sister's head with the false information. If it was her ex-husband, it can be chalked up to his trying to cause as much damage as he could as a form of retaliation against you for "meddling" in his family problems.

Under no circumstances should you involve your sister's children in this mess -- and that includes giving them any "messages" for their mother. You should, however, either try to reason with her via telephone, e-mail, a personal letter -- or even a meeting in person, if she's willing. And that's all you or anyone can do. The rest is up to your sister.

DEAR ABBY: Two years ago, my only child, "Gwendolyn," who is now 32, had her first baby. Unfortunately, the baby was born during the exact week that my husband -- her stepfather -- and I attend his family reunion. (It is something we have done for the last 15 years.)

Gwendolyn is now incensed because we plan to attend the reunion instead of her baby's birthday party. (We were with her for the baby's birth and his first birthday party.)

I offered to compromise by having a separate celebration either before or after the reunion week, but she refused. She accuses me of putting my husband's family ahead of her and does not understand why we can't postpone or change our plans. Abby, my husband's family is scattered across the country and this is the only time we see them. Can you offer me any advice? -- PULLED IN TWO IN S. CAROLINA

DEAR PULLED IN TWO: Only this: Alternate. Next year attend the birthday party, the following year go to the reunion., etc. Attendance at either one is not, and should not be, a command performance.

DEAR ABBY: When you have a houseguest visiting in your home and you are invited to another person's home for a party, what's the polite way to deal with the visiting guest? What would you do? -- CURIOUS IN CINCINNATI

DEAR CURIOUS: If it were me and the invitation came during the visit, I would explain to my prospective hostess that I had a houseguest staying with me. That would be the party planner's cue to say, "Why don't you bring your friend? I'm sure we'd love to meet him/her." And if that didn't happen, I'd politely refuse the invitation because I already had a previous social obligation to my houseguest.

DEAR ABBY: I'm in my early 20s and very much in love with "John," the man of my dreams. I know what I want, and I'm on the road to achieving it. I have had my "fun," and hope one day to start a family. Granted, it may not be for another two, five or 10 years -- but hopefully sooner.

This brings me to my predicament. John has told me he's not sure he ever wants to marry. He assured me that if, one day, he decides to be married, if it's not to me, then it will be to someone just like me.

I think John is worth waiting for while he decides, but I refuse to be his girlfriend for the rest of my life. Much as I love him, it would devastate me 10 years down the road if he finally decided not to marry at all.

I don't know what to do. I live on my own with no mother to run to for advice. I have always taken your answers to heart and applied them to my own life. Your advice would be greatly appreciated. -- MINDY IN SOUTH CAROLINA

DEAR MINDY: John may be an absolute doll, but you have described someone who has made it plain he is not ready for a serious commitment. Has it occurred to you that he may be trying to keep you from getting your hopes up where he is concerned? My advice is to keep your options open, and do not sit around waiting for him to grow up and recognize what a catch YOU are.

DEAR ABBY: As an active member of Overeaters Anonymous, I am open and honest with friends about my commitment to better health and understanding the foods I can and cannot eat. I am hoping you can provide me with a kind and gentle response to someone who presents me with a special dessert that she (or he) may have spent hours preparing.

My life and attitudes have changed greatly since I joined OA, and I would give away this freedom from food obsession to everyone I know if it were possible. -- C.T. IN BOULDER, COLO.

DEAR C.T.: Congratulations on your abstinence. When you are confronted with an elaborate dessert you can't eat, say, "I know you worked hard on this. But I can't accept it. I have food issues. I'm addicted to sugar, and once I start, I cannot stop. So please understand."

And unless the person is a diet saboteur, she (or he) will back off.

DEAR ABBY: How does one tell a friend that the tattoo she got in honor of her recently deceased friend is misspelled? Or should one? (I don't think most people would have noticed the misspelling, for what it's worth.) -- GOOD SPELLER IN PASADENA

DEAR GOOD SPELLER: Sometimes the kind thing to do is to keep one's mouth shut. If this were something that was easy to fix, I'd say tell your friend in English, and fast. However, because it's not, my recommendation is to let someone else give her the bad news.

DEAR ABBY: I have a friend who, last year, became the guardian of her 3-year-old granddaughter. This has severely curtailed her dating due to the need to hire baby sitters.

If a gentleman knows her circumstances and asks her out anyway, who is responsible for paying the baby sitter? -- K.B. IN MACON, GA.

DEAR K.B.: Since the child is her responsibility, it is her responsibility to pay for the baby sitter. However, if the "gentleman" knows it will strain her financially -- and he can afford it -- he should offer to pick up the tab.
