     I first went to Harrow in the summer term. The school had the biggest swimming pool I had ever 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? 1 decided to apologize immediately. "I am sorry, "I said,"I mistook you for a Grade Four

boy. You are 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.
