Several years ago I got an email from NAMI, the National Alliance on Mental Illness. They asked me if I would be one of their speakers at a training seminar they were giving. I marked it on my calendar and when I got there no one else had shown up. I spoke to the lady in charge of the facility and after a lot of looking on her calendar and making phone calls it turned out that I was early. By a month.
This was on a Friday so I drove across town to attend a public speaking group I was trying to decide whether or not to join. I helped set up the chairs, shook hands with a lot of people, even got to speak a bit.
Afterwards I met my wife for lunch and as we sat at the table I told her about my day. She looked at me and then said: “How long has your shirt been buttoned up wrong?”
