Attachment to Anger

A number of years ago, I had many difficult interactions with a co-worker. He did some terrible things, was dishonest, and caused much suffering among those around him. Then he moved on to another place. The other day I learned that he had been fired at his current job. My first reaction was to be cheered by the misfortune he had brought on himself. Of course, this was attachment to my own anger and suffering, even though it was many years ago.

My teacher has a bumper sticker on his car "Mean People are Suffering". I am not yet there...
