It is very exciting to walk into a glass door. I did it today on the way to the dentist. I was walking towards the assistant who was sitting at her desk - she was about 20 feet away and I smiled and then 'WHAM' I was staggering backwards holding one hand to my head and hopping. It was just like a panel in a comic book in which the superhero hits someone and they see stars and their eyes get spirals in them. I was totally stunned.

A few seconds later I realized I had walked into a door.

Nicole (the receptionist) asked "are you alright?"

I said "No, I don't think so" and collapsed in a chair.

My knee was very sore and I had a bump on my forehead that will be a bruise tomorrow. I asked for ice and lay in the dentist's chair with a baggy of ice on it throughout the exam.

Everyone in the dentist's office knew I was the one who walked into the door.

Josh was the most comforting. He told me that he has also walked into a glass door - on the way to his first Kung-fu class. Immediately, I felt affirmed as one of the herd of people who walk into doors but are not idiots, or are, but are social about it.
