I can remember the first time I had to go to sleep. Mom said, "Steven, time to
go to sleep." I said, "But I don't know how." She said, "It's real easy.
Just go down to the end of tired and hang a left." So I went down to the end
of tired, and just out of curiosity I hung a right. My mother was there, and
she said "I thought I told you to go to sleep."
