Analysis:

Then analyze them one by one.

First of all, talk about meanness. Mean is everyone's, and no one likes to give their things to others. This is the selfish side of human nature, which is normal. How to change it is a matter of degree. There is no need to care so much about things that do not harm your own interests. For example, what does it matter if you eat separately? Others use your things, and it won't hurt to use them, will it? As for valuables or money, you should consider it as appropriate, and you can decide whether to take care of it or not. If you have any jokes or group activities, just let yourself go, never mind. In short, open-minded people are much happier.

Sensitive and sentimental, which touches on a person's inner nature. Don't think too much. Like Lin Daiyu, fallen leaves are sad in the final analysis, so where is the fun of being a man? Smile more and encourage yourself more. No matter where you are, whether you are happy or frustrated, a person's life is short. If you are unhappy about what you can't change, it's not worth the candle. Change yourself and relax. What's the worst-case scenario? Will anyone die? No, since you can't, why are you so particular? Facing your inner feelings is more important than anything else. Don't forget that there is only one you in this world. Be kind to yourself.
