What should I do if I meet someone I don't know but laugh at you?

When the forest grows up, there are all kinds of birds, and there are so many people in the world. There are many people like me. No matter what he says or does, there is something wrong with this kind of person. Do they laugh at others because they think they are great? In fact, such people are not as good as you. They are arrogant and only look at other people's jokes, but they don't know that they are also jokes. If you talk to him, he will feel good. Don't get used to him and ignore him. You should do it yourself.
