On the inbound M train this morning, the man sitting across from me laughed out loud. If you audibly laugh on MUNI, and you are not in conversation with another rider, this usually means that you are crazy. However, it appeared that he was simply struck by an especially funny passage in his book.
This intrigued me. What was he reading, I wondered. The book was on his lap, so I couldn't see the title. I glanced surreptitiously around my own book and waited. When he finally got up, the mystery was revealed: Our Endangered Values: America's Moral Crisis, by funnyman Jimmy Carter.
