     Jess really felt very happy. When he arrived at his seat in the classroom that morning, he found an invitation (请柬) on his desk. It was from several of his classmates asking him to join them in a camping trip. This was

the first time he had been asked to join in an out-of-school activity. Why were they asking him now? Nobody

seemed to like him. In fact, he had been so lonely that he drowned his feeling with food. As a result, he had

put on a lot of weight and this gave the kids something more to make fun of him.

     Cindy, who was standing near Jess when he read the invitation, went out quickly to tell the others that the

trick (恶作剧) had worked. Everyone was pleased that Jess thought that was true. But there was no camping

trip. The whole thing was made up.

     At first, Cindy thought it was fun. But later, when Jess told her that he was going to buy a sleeping bag with

his savings (积蓄), Cindy had a second idea. She knew that Jess's family had little money, and she hated to see

him spend his savings on something he would never use. Cindy also hated to tell Jess the truth. Her close friends would be angry with her.
