Example: There was a truck driver in the film that was subject to road rage. He ranted and raved about the drivers out on the road...finally the guy asked him, "Why do you expect these drivers to do right? You see this everyday--why should it be any different than what it is?" Guy was like, "I don't know--it just ought to be. They should drive like they have sense and I get mad when they don't." He was told his anger came from his expectations and not what was based in reality.
I can see what the guy was saying but still...I don't necessarily agree with it all.
