There was a man who lived on the 12th floor of an apartment building. Every morning he would take the elevator down to go to work. If it was raining, or if there was someone in the elevator with him when he came home, he would take the elevator all the way to the 12th floor. But if the weather was good, and he was alone in the elevator, he would go up to the 7th floor and take the stairs the rest of the way up. Why?
