Dear Ann Landers,
My 21-year-old stepson lives with my husband and me. He is a good student at a nearby college and doesn't drink or do drugs. He does, however, bring his girlfriend home frequently, and she stays until the next morning -- in his bed, I should add. My husband doesn't see anything wrong with this, but I believe unmarried people should not be having sex, and they certainly should not invite their girlfriends to stay overnight when they are living in their parents' home. How can I convince my husband and stepson that this is not appropriate behavior? -- Out-Voted in California

Dear Out-Voted,
I agree that it is not acceptable for your stepson to invite a young woman to stay overnight in your home without your approval. But you are not going to change the behavior of a 21-year-old and shouldn't try. You do, however, have the right to say, \"NOT IN OUR HOUSE.\" Tell your husband I said so.
