Mr. White is very busy today. He helps his mother move into a new house. He starts at 3:30 in the afternoon. First he cleans the windows. Then he carries all the heavy furniture (家具) into the new house. He helps his mother put the curtains (窗帘) up too.

Mr. White is very tired when he gets “home”. It is 9:15 p.m. He can’t find the right key to the front door. The front door is locked. Then he tries the back door, but it is also locked. “I should climb in through the kitchen window,” Mr. White says to himself. He doesn’t want to wake up his wife and children.

But suddenly, a big black dog comes to him from behind. Mr. White is afraid and surprised. He doesn’t own a dog! He is at the wrong house! Soon the police come. “I’m not a thief (贼) or a robber,” says Mr. White to the police. “I’m at the wrong house. Please believe me.” What an unlucky poor man Mr. White is!
