One morning, George left his house with six donkeys（驴）to the market. He counted them every few minutes. When he felt tired, he found there were only five donkeys. He got off the donkey's back at once and went to look for the sixth. He looked for it everywhere but didn't find it. He had to go back to the donkeys with nothing. And counted them again, there were six this time! So he rode onto one donkey's back again and continued going.
After a few minutes, he counted the donkeys again, and again. There were only five again! When he was counting again and again, "I left my house with six donkeys, then I had five, and now I have only five again! Look! One, two, four, five. How strange it is!"
"But, George, " said his friend, you have seven donkeys— you are the seventh! "
