As I was driving home from dropping my daughter off from school, I saw another parent casually telling a joke to a crossing guard, whose reaction was so over the top it left him visibly shaken. I don’t know exactly what he said to her, but I’ve been there. A buddy of mine in high school, if you told him a lame joke, would do exactly this. At the time it was horrible, but it’s sort of funny to think of now.
