Last night, after arguing with Evan but before yelling at him, I was ready to hop the Clark bus at Diversey. The bus door opened, I waved to Evan, and as I was getting on, the driver said, "Get on if you're going to get on!"
So I justifiably replied, "I'm getting on. You don't need to be rude about it." And then four exchanges each of this: "No, you're rude!" I got the last word in.
