A mother and son were washing dishes while the father and daughter were watching TV in the room. Suddenly, there was a crash of breaking dishes, then complete silence.

　　The girl looked at her father and said, “It was Mom”。

　　“How do you know?” asked her father.

　　“She didn't say anything.”

　　I Have Turned It Over

　　A woman said to her husband, “dear, look at our sheet! It's too dirty. Would you like to wash it now?”

　　The man looked at the sheet and then thought for a while and then said, “I don't think it's necessary. We can turn the sheet over. Is that all right?”
