He was wearing a Harvard backpack with the logo prominently displayed on the back, and it was right in my face. He had cut like 10 or 15 spots. I wanted to strike up a conversation with him, asking if he was a student or a professor there. Then after playing nice for a bit, ask him which class he failed - was it math or ethics? Because it was pretty clear that either he was having trouble counting, or he was having trouble understanding that cutting in line was a jerk thing to do.

Funny how a smart guy like that can fail to understand such basic principles...
