On an old "Amos and Andy" television program, Andy was angry. There was a big man who would continually slap Andy across the chest every time they met. Andy finally had enough of it. He told Amos, "I'm going to get revenge. I put a stick of dynamite in my vest pocket. The next time he slaps me on the chest he's going to get his hand blown off." But Andy forgot that the dynamite would also blow his own heart out. Revenge may hurt the other person but it always blows our own heart out.
