The school had the biggest swimming pool I had even seen. It was a good joke to come up behind a naked boy, and push him into the pool. I made quite a habit of this with boys of my own size or less.     One day I saw a boy wrapped in a towel on the side of the pool. He was no bigger than I was, so I thought him a fair game. Coming secretly behind, I pushed him in, holding on to his towel so that it would not get wet. I was surprised to see an angry face come out from the water, and a being of great strength making its way by fierce strokes(猛力地划) to the shore. I fled, but in vain. He overtook me, seized me violently, and threw me into the deepest part of the pool. I soon climbed out on the other side, and found myself surrounded by a crowd of younger boys. "Do you know what you have done?" they said. "It's Amery; he is in Grade Six. He is champion at gym；he has got his football honor. "     I was frightened and felt ashamed. How could I tell his position when he was wrapped in a bath towel and so small. He didn't seem pleased at all, so I added in a most brilliant word, "My father, who is a great man, is also small." At this he laughed, and after some general words about my rude behavior and how I had better be careful in the future, signified the incident was closed.1.
