You know a chaperoned blind date went well when:

1. No one ran screaming from the building at first meeting.
2. The main fidgeter was one of the matchmakers, not the two parties who had never met.
3. Everyone had a good time.
4. Everyone relaxed after the first few minutes.
5. Everyone had a free-for-all at the dollar book table at the end. Oh. Maybe that's not your ideal ending to a date. But it worked for me. ;)

I'll write more later.
