Yes that is the guy. He does a TED talk if you want the short version, but of course I recommend the book. After reading it I asked my three kids if they wanted to spend a day in silence and they enthusiastically said yes (weird huh?). Then I added that instead of staying home we were going to travel the county, on a bus, and interact with people all day. It was a very memorable day, with many challenges, but we had a lot of fun. I know I learned a heck of a lot that day (one thing was that people would almost yell when trying to converse with you after they realized that you were not talking or hearing).
