I think most people don't understand that discipline doesn't mean making someone's life hell. It comes from the Latin word meaning "to teach". So if taking this guy's car away teaches him that drinking and driving is bad and he doesn't do it again, then goal accomplished. Everyone doesn't need the hammer to fall on them to teach them lessons. Some people may need to be kicked off the team, some people may need to go to jail, the fact that Bert called his mom shows that he understands that everyone isn't the same and using the same tactics in every situation is unwarranted. I think Bert is a probably a jerk, but I think he probably did the right thing in this case.
P.S. Every time I post from work it ends up being a double or triple post. If that happens I apologize, I just felt the need to share on this topic.
