You don't need so many tricks. You just need to remember the following points. 1 Don't talk about others behind their backs, because it will always reach others' ears. It is better to tell the truth. You can make a joke, but don't involve other people's privacy, otherwise it will make a big joke. People will hate you. Don't use your own point of view to affirm other people's behavior. Because sometimes we only know the surface. Treat every friend sincerely, don't think they are treating you.
