    Stealing? Maybe, but in our 1  minds we were just enjoying nature's gift.

    As teenage boys, we were not thinking about whose the strawberries were. We 2knew the Jordan family had the best strawberries in the neighborhood.

    So on a Friday3 , we secretly went into the Jordans' backyard and started picking their sweet strawberries. We thought there was 4 that tasted better than the fresh strawberries. 5 we were enjoying the delicious strawberries, suddenly the Jordans' backyard 6  came on. It was terribly bright, so we hurried to cover our faces with hands. Then we saw 7 ran outside.

    “What are you boys doing out here?” he shouted 8  as my friends ran off in all directions. They were so9  that the older gentleman couldn't catch them. And at once all the boys ran away into the dark, except 10 .

    Mr. Jordan shouted at me as he ran after me all the way to my house, which my mother was in. My mother said11  over and over again. I felt so embarrassed (尴尬的). My friends said they could hear 12  she said to Mr. Jordan from our backyard. My friends laughed at me about it for days later.

    I was down and complained (抱怨) to my father. After hearing that, he said, “I don't think it's unfair at all. You took strawberries without 13 , and you got exactly the punishment you should have.”

    “But what about the other guys?” I asked. “They weren' t 14 at all!”

    “That should not be what you are thinking about,” said Dad. “You can't 15  what happens to other people, but you can do your own job well. You made a bad choice that night, and you were punished for it. ” That sounds completely fair to me.
