For shame

People say they can tell when their dogs are ashamed but I have my doubts. Your average dog brain is about the size of a cue ball and just as smooth, lacking convolutions wherein regret might lodge. Humans on the other hand have all these notches and crannies that promote the construction of narratives. That means as we get older we build a richer story, gain a sense of perspective. So instead of tormenting yourself about some dumb or unkind thing you did last week, you can torment yourself about some dumb or unkind thing you did 50 years ago.
