Dear Abby, A couple of women moved in across the hall from me. One is a middle-aged gym teacher, and the other is a social worker in her mid-twenties. These two women go everywhere together and I've never seen a man go into their apartment or come out. Do you think they could be Lebanese? Dear Abby, What can I do about all the sex, nudity, language and violence on my VCR? Dear Abby, I have a man I never could trust. He cheats so much I'm not sure this baby I'm carrying is even his. Dear Abby, I am a 23-year-old liberated woman who has been on the pill for two years. It's getting expensive and I think my boyfriend should share half the cost, but I don't know him well enough to discuss money with him. Dear Abby, You told some woman whose husband had lost all interest in sex to send him to a doctor. Well, my husband lost all interest in sex years ago and he IS a doctor. What now?
