I was once amused by a very simple answer from a maid. When somebody came to the door and knocked, the maid was not free to go at once but took her time. When at last she came, the man was very cross and said, "Why did you not open the door quickly?" I asked the maid, "What do you think was the reason for the person's being cross?" She said with her innocent expression, "Because there is no God with him."
