"Being a childless woman of childbearing age, I am a walking target for people's concerned analysis. No one looks at a single man with a Labrador retriever and says, "Will you look at the way he throws the tennis ball to that dog? Now there's a guy who wants to have a son." A dog, after all, is man's best friend, a comrade, a pal. But give a dog to a woman and people will say she is sublimating. If she says that she, in fact, doesn't want children, they will nod understandingly and say, "You just wait." For the record, I do not speak to my dog in baby talk, nor when calling her do I say, "Come to Mama."
