Looking at your personality and the way you treat your friends, some people think that friends are contacts, and he will pay for anything that is helpful to his own development. He doesn't just pay for everyone. This kind of person only pays for things that help him, and his personality is decisive and straightforward.

If you are introverted and don't like to talk, you may not like making friends, because making friends requires entertainment and maintenance, and you won't feel trouble.

But then again, the friends you make now are only superficial friends, and everyone values class. If you want to make friends with people who are helpful to you, you should also be useful and valuable. They are mutual. What kind of people will attract what kind of people.
