There is a colleague, he fights, I am afraid he will suffer, I try my best to fight, others quarrel with me, he doesn't say a word, watching a joke! Why is there no conscience?

Making friends depends on whether you are really with you. In the face of some important issues, if your colleague can be like you, then he is a true friend. If this happens to him now, don't associate with her, and don't try your best to pull when he fights with others. Such a person is not worth making friends, because in the face of such right and wrong, you can see this person's character.
