“One afternoon, I went to a shop to buy some ink. There was only one young shop assistant in it. He was reading a book.
“I want to buy a bottle of ink,” I said. There was no answer. He was still going on reading his book. Then I asked again.
He stood up and gave me a bottle of ink. When I was out of the shop, I found the change he gave me was too much. So I went back to the shop. The man pulled a long face when he saw me again.
“Now, what do you want to buy?” he said angrily.
“Nothing,” I said, “you gave me too much change just now. I want to give you back the money.”
“Ah, ah, thank you,” the man said with a red face.”
