一辈子记住，这五个没必要。讨厌一个人，没必要翻脸；喜欢一个人，没必要卑微；错过一个人，没必要怀念；看穿一个人，没必要揭穿；离开一个人，没必要伤害对方。

Keep these five "unnecessary" principles in mind for your whole life: There’s no need to fall out with someone you dislike; There’s no need to be humble in front of someone you like; There’s no need to dwell on someone you’ve missed; There’s no need to expose someone you’ve seen through; There’s no need to hurt the other person when you part ways.
