Over the past years I've driven many, many miles on Los Angeles freeways in conditions of heavy to light traffic. In that time I've seen lots of different, interesting, and sometimes even scary things being done on the road. Today was something I've never, ever seen before. I got to spend about 15 minutes in traffic going through downtown behind a couple in a car having a very animated discussion. Their car had a huge un-tinted back window which afforded me an excellent view into their car.
The discussion went back and forth until finally one participant picked up the newspaper and defiantly read it while facing the side window away from the driver. Normally that wouldn't noteworthy or interesting, but what made this conversation special was that the participants were deaf and communicating in sign language. The passenger had an easy time of it, of course, but the driver was essentially talking with one hand while trying to drive and watch the passenger's replies. Needless to say the passenger was having a hard time getting their opinions in as the driver spent much time looking forward while continuing to talk. This precluded the driver from seeing the passenger's attempts to interrupt.
The world is a fascinating place.
