I think Yu Youjin should be divided into two situations. The first kind is a joke, because online words are popular now, and many people will take out the word "friends are exhausted" to joke with friends. This situation is very common, and I think many of my actions will make a person feel this kind of emotion; There is also a feeling of being really heartbroken. You feel that your friend doesn't treat you as a friend, and then you feel that he may not be a person worth making friends with.
I have such a person around me, who often jokes that many things about her make me feel friends. I once had the kind of person who used to be good friends, but because of some things, I felt friends, and finally went further and further, and now I have no contact. For friends, these are normal, because people's emotions are subjective, and you don't know when you will feel this way about people around you. The friend mentioned, she often makes me joke that she will make me feel friends. Because she often puts people in an awkward position, but this kind of embarrassment is excusable, and then she told others around her that they felt the same way, and then she let it go. Maybe that's her personality.
But there are some behaviors that I can't stand. For example, sometimes she may lie to you, but this lie is unforgivable. When you found out, she didn't want to explain it to you. I think at this time, she may not regard you as a friend at all, so there is no need to continue this relationship, even if it is a white lie. I have a friend because of this, so I have no contact with her at all. There is also your friend. When what she says is different from what she does, I think it may be that there is something wrong with her character. I don't like to associate with such people.
