What is forgiveness, and what kind of behaviors and things are forgiven?

I think I will never forgive those who have hurt me. If one day I communicate with those people normally, it's not that I forgive them, it's because I think these things have passed, not that I forgive them. In fact, when everyone grows up, they will encounter things that they feel particularly unforgivable, but others may think that these things are particularly indifferent. Everyone has something that everyone cares about. Some people especially like to joke about things you care about, and then you get angry, and they will think you are so stingy. In fact, I really hate this kind of person. If you don't know where other people's pain is, don't say it there. I especially like a line sung by Roy in a song. No one in the world really feels the same way. Where in the world do you really feel empathy? What you experienced, she didn't experience, and what she experienced, you didn't experience. You two don't have the same pain at all. How can you feel the same? If you are angry, they will think it is a trivial matter. Why are you so angry? It didn't do you much harm. They will persuade you to forgive that man. But I won't. I feel that since he has done something unforgivable, he should not forgive her. One day, if there is really no way to communicate as before, I think it's just forget it, not forgive it. I will never forgive those who have hurt me. It is possible that a joke played by others will cause a psychological shadow in your life when you are young. Then why should we forgive them? If we forgive them, how can we be worthy of ourselves who have suffered? If you forgive them so easily, can we be worthy of ourselves who cried at night? I don't think some people should be forgiven and I won't forgive them.
