What absurd things have you done because of your own hindsight?
I especially like to play when I am reading. I have to put off my homework until evening every day. Once I played a game for a long time. Finally, it's already three o'clock in the morning, but I still think I can finish my homework. As a result, I didn't finish my homework at school, and then I was called to the office by the class teacher and criticized. I thought it was ridiculous afterwards. I don't understand why I didn't even finish my homework, and this is not the first time.
