I'm sorry, but stay with me. If it's just a tiny scratch, you barely notice it. You'll probably forget it in a day or two. But if it's a deeper cut, one that stings and makes you say, ouch, you remember it way longer, don't you?
我很抱歉,但請聽我說。如果只是很小的劃痕,你幾乎不會注意到。可能一兩天就會忘記。但如果是更深的傷口,刺痛得讓你 "哎喲 "一聲,你就會記得更久,不是嗎?
