People are like this. No matter where they are, they will feel sad when they see others' dribs and drabs about themselves, or when they say that they are not nice, because they care too much about other people's opinions. I don't want to hear others say that I am not good, and then if I convince him, I will be much more comfortable when I go back. This is everyone's psychology, because he said a bad word about me, so I have to go back, so I will be comfortable.
