DEAR ABBY: Last December, we invited some out-of-town friends to spend the holidays with us. They have children and two dogs, which they take everywhere. We are not very fond of having animals in our house, but we really wanted to see them, so we told them to come and bring their dogs on the condition that the dogs be put out on the patio while we ate our meals. (If you don't, the dogs are under your feet at the table.)

Well, the dogs were put out only during the Christmas meal - otherwise they were under our feet during breakfast, lunch and dinner. They also got up on the furniture, and even slept in bed with our friends!I do not dislike animals, but I had a couple of childhood incidents with dogs that left me uncomfortable around them.

I didn't say anything to my guests at the time, but we would like them to visit again - without their dogs. How can I get them to understand our feelings? - BAFFLED

DEAR BAFFLED: By not reinforcing your conditions, you have already set a precedent. Why not tell them what you told me? You can even show them this letter, but don't expect them to understand your feelings. People whose pets sleep with them regard their pets as their children.

DEAR ABBY: I am a 64-year-old man, but I look, feel and act like a man of 50. I play tennis three times a week and keep myself in excellent physical condition. I am engaged to marry a wonderful 40-year-old woman. It's the second time around for both of us. I have three grown sons. The lady I'm marrying is childless by choice and she's made it very clear that she wants no children.

Abby, does a man my age need a vasectomy? - LAS VEGAS LOVER

DEAR LOVER: Any man who is young enough to be a lover is not too old to need a vasectomy.

DEAR ABBY: I am writing to ask your opinion about a favor I recently asked of my aunt. She's my mom's sister. I asked her if the next time we see each other she would give me a mouth-to-mouth kiss. I am her oldest nephew (nearly 20) and she's in her late 30s. She is very good-looking.

Last New Year's when she gave me a hug and a little peck on the cheek, I asked her for a mouth-to-mouth kiss and she said, "NO!" When I asked her why she said it, she said it wasn't "proper" - then she said she has two boys of her own and she doesn't even kiss them on the mouth, and with that being the case, it wouldn't be fair to kiss her nephew on the mouth. What do you think? - SHUT OUT

DEAR SHUT OUT: Mouth-to-mouth kisses are for lovers - not relatives. Be satisfied with a hug and a peck on the cheek from your good-looking aunt, but look elsewhere for the kind of kisses lovers share.
