The last one

"So that's the last one, isn't it?" said the visitor, looking at the animal in the cage.

"It isn't very interesting, is it? What does it do all day?"

"Nothing," replied the zoo keeper. "It just sits there looking unhappy."

"I am not surprised it is almost extinct now. It does not look strong. It is quite ugly, isn't it?"

"I believe they can be dangerous when there are a lot of them. But it is sad to see an animal become extinct."

"Well, it is for some animals, but I really don't think the world will be less beautiful when it goes," said the visitor walking away.
