This question depends on your personal situation. Different personalities, hobbies, experiences and occupations determine that different people have different requirements for their circle of friends. I have a wide range of personal hobbies, both solitary and lively; Sometimes it's old-fashioned, sometimes it's just a joke. No one is perfect. I make friends on the basis of his merits. As long as he doesn't have anything that goes against the basic social morality, as long as he has a little strength or something similar to me, I am willing to associate with him. Of course, according to the situation of the other party, the number of contacts is different. Friendly and sincere. Communicate sincerely with others, be good at accepting different opinions of others, and seek common ground while reserving differences on unprincipled issues. Treat others sincerely and others will treat you sincerely.
