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.
我妹妹的手指頭
老師:凱溫,這次你怎么又遲到了?
凱溫:對不起,老師,我在家釘釘子,砸壞了兩個手指頭。
老師:怎么沒有扎繃帶呀?
凱溫:噢,砸的不是我的手指頭,我叫小妹妹扶著釘子的。
