Tom finished his middle school half a year before and then he worked for a postman in his small town. As he was afraid of dogs, he often had a lot of troubles. One afternoon, he tried to take a post card to a bigger house by bike. When he reached the house and got off from his bike at the gate, at once a large dog came run at him with much noise. Tom quickly threw the card through the gate. With his surprise, the dog didn’t make any noise. It ran fast to a card, picked it up with its mouth, carried it towards the house. Tom thought for a while and said to him, “The dog is a better postman than I am.”
