Mr. Henry has a son. His name is Billy. Billy likes playing games and doesn't like studying. When he can't do homework, he often asks his mother. But Mrs. Henry can't do it, either. She asks Mr. Henry to do all the homework for Billy every day. Mrs. Henry says she will do all the housework when Mr. Henry helps Billy to do the homework. And Mr. Henry doesn't need to any housework. So Mr. Henry is always willing to help his son to do the homework.
It is Sunday today. Mr. Henry has a lot of clothes to wash. Mr. Henry hates to do washing. So he asks his son, “Do you have any homework to do, Billy? Let me help you!”
“No, today is my lucky day. I don't have any homework today. ” Billy says happily.
“Bad luck! Today is my not my lucky day.” says Mr. Henry. “I have to wash the clothes today!”
