A Man in an Elevator A man who lives on the tenth floor takes the elevator down to the first floor every morning and goes to work. In the evening, when he comes back; on a rainy day, or if there are other people in the elevator, he goes to his floor directly. Otherwise, he goes to the seventh floor and walks up three flights of stairs to his apartment. Can you explain why?
He's too short to reach to 10th floor button. If there's others in the elevator, they can reach it for him, if it's raining he can push it with his brolly.
