It’s time to go home now. I’m in a bus on a rainy day. A woman with a dog gets on the bus. The woman is well dressed( 穿着华贵的 ). She is very fat. And her dog is fat, too, but it’s not clean.

I don’t want the dog to sit near me. But the woman says to the conductor, “Oh, I pay for my dog. Can he sit here like the other people?”

The conductor looks at the dog and says, “Yes, but like the other people he must not put his feet on the chair.”
