I had a management class years ago, where the instructor talked about others taking control of your life. It happens when somehow an event bothers you so bad that you can't let it go. Especially events that don't directly affect you. The perfect example is when you are driving and another car pulls out in front of you. Then you go to work and tell your workmates, then you go home and tell your wife, and so on. The other person now has taken control of your life.
Well, Greg, you definitely own some BF'ers at this point.
