Bill and Fred studied at a university and they were friends. They didn't have much money, so when it was time for their holidays, Fred said, "Let's take our holidays in a trailer[1], Bill. It's cheaper than a hotel. I can borrow my father's trailer."
Fred was very happy. So they got into the trailer and began their holidays. They wanted to get up early the next day to go fishing, but they didn't have an alarm[1] clock.
"That's all right, Bill," Fred said. "I'll put these pieces of bread on the roof[3] of the trailer tonight and they'll wake us up in the morning." Bill was very surprised, but he didn't say anything.
Fred was right. As soon as it began to get light, small birds came down to eat the bread, and their noise on the roof of the trailer woke Bill and Fred up very quickly.
