Why do some friends always like to attack me and dig at me? What kind of mentality should I face such a friend?

Some people do this because their mouths are poisonous, but they just talk casually and are not at ease. But this kind is rare. Most of them highlight their Excellence by cracking down on sarcasm. If you are good friends, you can adjust yourself and have a good talk with your friends without great psychological trauma. But if I am an ordinary friend, I will choose to reduce or cut off contacts.
