     Thanks very much for your story. The plot is very touched. OK, now listen to me carefully. It’s very

funny. One day, a young man was going from house to house on his street so he wanted to introduced

him to all his new neighbors. Outside one house, he stopped and saw a big dog sitting on the sidewalk.

Well, he thought that it was belonged to the people in the house, but he paid no attention to it. He just

pressed the bell, and the owners asked him in, and the dog went in, either. He greeted them with a smile

and then he sat down, and a couple gave him a cup of coffee and some cookies. Well, the dog ate one

of the cookies off the plate, and sat in his knee. The young man don’t want to seem rude, so he petted

the dog gentle and continued talking to the couple. Anyway, when it was time to go, he thanked them

and left. When the young man left, the woman called after him, “Excuse me, don’t forget to take your

dog!”
