你跟我说一下不就行了吗？

　　No good deed goes unpunished. I had volunteered to tar the roof on my father's shed. I was about halfway done when I slipped and fell flat on my face getting black goop all over my shirt, my pants, even my hair. Hearing the thud, Dad looked up. "What happened?" I got up and began to say, "All I did was..." when my feet shot out from under me and I flipped into the tarry mess a second time. "You know," Dad said dryly, "you could have just told me."

　　真是好人难做！ 那天，我自告奋勇去给我父亲的(工具)棚顶上柏油。快上到一半的时候，我在上面滑了一下，直挺挺、脸朝下地摔在了房顶上，结果弄得衬衣、裤子甚至头发上都满是糊块。 父亲听到响声，抬头问，“怎么回事？”我爬起来，正开始说到，“我刚才是... ...”时，我的双脚突然一滑，我第二次趴到了那堆柏油上面。“呃，” 父亲若无其事地说，“你告诉我不就行了吗？”
