I met my friend the test pilot, who had just received a lot of publicity for a record round-the-world flight by hot-air balloon. With my friend was a little girl of about two. “What’s her name?” I asked my friend, whom I hadn’t seen in 5 or 6 years and had married in that time. “Same as her mother,” was the reply. “Hello, Susan,” I said to the little girl. How did I know if I had never seen the wedding announcement?
