扣子掉了

今天去学校的路上，我衣服的扣子突然掉了。那时候我已经到了车站，本来想回家改外套，但是我已经迟到了，所以我选择去学校，然后去买回形针。我进嘟嘟车的时候，我记得我有社团名牌，所以我就用它了。既然没有人发现我是这样用社团名牌代表扣子，或者他们注意，但是没说。

On my way to school today, a button suddenly removed from my jacket. I had already reached the bus station by then. I originally wanted to go home and fix it, but I was already late, so I chose to head to school and planned to buy a paper clip there. When I got into the tricycle, I remembered I had my club name tag with me, so I used that instead. Since then, no one noticed that I was using a club tag as a button, or maybe they noticed, but they just didn't say anything.
