My Sister's Fingers Teacher: Kevin, why are you late this time? Kevin: Please sir, I bruised two fingers knocking in a nail at home. Teacher: I don't see any bandages. Kevin: Oh, they weren't my fingers! I told my little sister to hold the nail. 我妹妹的手指头老师：凯温，这次你怎么又迟到了?凯温：对不起，老师，我在家钉钉子，砸坏了两个手指头。老师：怎么没有扎绷带呀?凯温：噢，砸的不是我的手指头，我叫小妹妹扶着钉子的。
