A Couple Had Fight

A couple had fight and did not talk to each other. One day, because the husband had to wake up early the next morning, he needed his wife to wake him up around 4 am. But he did not want to talk to her first so he grabbed a paper and a pencil and wrote, "wake me up around 4. I have to get up early for my job."

The next morning, the husband was so furious because he woke up around 9. He was late because his wife did not wake her up. Then he saw a note at the table beside the bed, "wake up. It's 4."

Sorry for my bad english.
