Ever push an elevator button, only to have someone else walk up behind you and push it again? I have trouble not taking this personally. Yesterday, I said to a young man who followed my push with a few repeated jabs of his own, "Oh thank you, I wasn't quite sure how these new-fangled elevators work." Is there something that makes us assume that the more you push the button, the faster it will come? By the way, when the elevator arrived, I stepped in and pushed a few extra buttons, and said... "Oh sorry. Was that wrong?"
