Last Sunday, the Green brothers, Tom, Tim, Tab, went to a restaurant and wanted to have some food. The restaurant was very nice. It sold different food. Tom ordered (点餐) fish and chips. Tim ordered a sandwich. And Tab ordered a hamburger. When they waited for the food, they found that they didn't have money. "We forgot the money and can't pay (付款) for our food." Tim said. "Tab can go home and get the money, because he is young." said Tom. But Tab wasn't happy to do so. "Ok, I'll go, but you can't eat my hamburger." Tab said. Tom and Tim said "Yes!" Then Tab left. When Tom and Tim saw Tab's hamburger, it looked very nice and smelt very delicious. "Let's eat Tab's hamburger." said Tim. Then they touched the hamburger. As they did so, Tab shouted from the door of the restaurant, "If you touch my food, I won't go home for the money."
