Why am I kind to a classmate? But he turned to attack me and deal with me. Is it the story of Mr. Dong Guo and the wolf? He gave me a distant friend and a near attack.
This means that you associate with junk friends and junk classmates. It's okay for such classmates not to associate with each other. People have good and bad feelings, and they attack you. Either you provoke him yourself, or he doesn't like you and wants to find an excuse. Such people stay away from good intentions. Sometimes good intentions don't pay off in society, so be more concerned.
