Teacher: Kevin, why are you late this time?
Kevin: Please sir, I bruised(擦傷) 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.
老師：凱溫，這次你怎麼又遲到了?
凱溫：對不起，老師，我在家釘釘子，砸壞了兩個手指頭。
老師：怎麼沒有扎繃帶呀?
凱溫：噢，砸的不是我的手指頭，我叫小妹妹扶着釘子的。
