I've done almost all of my Christmas shopping but today I had to do a little last minute shopping. What is it with people behind wheels at this time of year? A minority, a very noticable minority, of them go crazy just before Christmas. They become rude, aggressive, monsters that will risk lives to get a parking place. Even in Oklahoma, where most drivers will stop to let pedestrians cross a street (try that in Dallas!), the normal civility is hard to find at these times.
