Don't worry too much about this, just like falling in love. At first, you don't know who you are in tune with or who you can talk to. Making friends depends on the similarity of personality and some opinions. Some just hit it off, and some just feel that there is a distance between you. In addition to let yourself grow up and find a place to learn from people you know, the problem you mentioned, the problem of true friends, is indeed that in real society, both colleagues and friends you know through some channels are partly influenced by the relationship between superiors and subordinates, work, family and life. In fact, very few people really make friends with you. Therefore, a person sometimes has no real friends all his life. As long as you make friends with others with your heart, no matter how sorry others are, it's their business, not yours. Because of carelessness, they may have several good friends in the future.
