DEAR ABBY: What do you think of parents who let a 17-year-old boy hang around their house all day and half the night, seven days a week? The boy is our son. "Scotty" has been going steady with a sexy little 16-year-old girl for nearly a year, and he practically lives at her house.

He says her folks have never asked him to go home, so he just stays. I say they should kick him out at midnight. We are so afraid that all that time together will lead to intimacy they can't handle. Any suggestions? - SCOTTY'S PARENTSDEAR PARENTS: Don't expect the girl's parents to discipline your son. That's YOUR job. Set some rules and a curfew for Scotty and see that he obeys them. In the meantime, Scotty's dad should have a man-to-man talk with him. An ounce of prevention is worth an eight-pound mistake.

DEAR ABBY: My aunt is a sweet lady who visits me frequently throughout the year. I love having her, but I do not love having her dog, which she absolutely refuses to leave behind in a kennel or with a friend.

I tolerate picking up the dog deposits in my yard, watching him eat from my dishes, begging at the table while we eat and sleeping on the bedspread in the guest room. But what irritates me more than anything else is the cleanup job I have to do after my aunt and her dog go home.

There is dog hair all over my carpet and every piece of furniture, and even at the bottom of my draperies. This dog also scratches himself constantly, so his dry skin leaves a pungent odor throughout the house. I have to use carpet deodorizer and air freshener, and I'm vacuuming constantly. I'm beginning to dread these visits from my aunt because I feel such resentment toward that miserable mutt!

I have absolutely no nerve when it comes to simply asking her to leave the dog at home, so I guess I'm stuck with the situation. However, this may alert dog owners never to assume that your dogs are welcome in other people's homes. Leave them with friends, professional dog-sitters or at a reputable kennel. - NO NERVE

DEAR NO NERVE: People with no nerve can expect to be imposed upon frequently. Do not expect your thoughtless aunt to read this and stop bringing her "miserable mutt" to visit you. She will either not recognize herself, or she doesn't give a hoot about how unwelcome her dog is. And by the way, don't blame the dog if his master doesn't care enough about him to take him to the vet's periodically to make sure his skin is not dry. Some people do not deserve pets, and your aunt is one of them.

CONFIDENTIAL TO "DREADING THE FAMILY GET-TOGETHER": Sorry your relatives are so boring. No one said it better than Ogden Nash: "One would be in less danger from the wiles of a stranger if one's own kin and kith were more fun to be with."
