text: what's the meanest, harshest, most cruelest thing you've ever done to someone?   i got my wife's boyfriend---the one she left me for---fired from his job.  i still think about that and smile.  i did lots of other stuff during those months that i'm not proud of, and are probably meaner, harsher, and more cruel.  i'm not proud of those, so i'll stick with the answer above.
