Their Usual Quarrels

Once a couple had one of their usual quarrels as a consequence of which all conversation between them stopped. Unfortunately the husband was to attend his office very early the next morning. So he wrote on a piece of paper, "Please wake me up tomorrow morning," and kept it beside his wife's pillow. His wife read it and went to sleep. He woke up very late the next morning and got very angry. He looked ferociously at his wife, but she calmly pointed towards his pillow. Under his pillow he found a piece of paper. On it was written, "Please wake up, it is 6 o'clock now."
