you know people that would get that worked up aover such a small thing as being cut off NEED HELP
( I am not talking about your friend, he aperently needs help too but in a diffrent way, I hope he is getting counseling) I deal all the time with people who are screaming and litteraly CRYING and FREAKING out over softwear. It's softwear folk, get real.
I have bad days too. I had one of the worst ever yesterday. I went home washed my car, had a nice dinner with one of my kids, played a game of chess had a glass of wine and talked it over with a good friend. I called my mom and cried. I went to bed early, thought alot about things, wrote in my journal, and got some perspective.
honestly in reality I think it is better to be a defensive driver and I rarely slowdown in front of someone to fuck with them.
seriously, people neeed to put things in perspective.
