A birth

Have you heard about the good news in the Wallace family? No, I've been out of town. Mrs Wallace went into the hospital last night and gave birth to a baby girl seven hours later. That's very good. But they already have a little girl, don't they? No, they have a 5-year-old boy. So they wanted a girl this time, right? Yes, they wanted a girl for a long time. Was it natural childbirth? No, she had to have a caesarean.
