Especially in love, it is clear that the other party has made himself suffer for so long, but after he heals the injury, as long as the other party gives himself a candy to eat, he will completely forget his pain and accept the other party again. I think this kind of behavior is torturing myself. Don't "forget the pain after healing the scar".
Some people have strong willpower. He knows it is difficult to finish, but he wants to do it well. But after choosing a certain scheme, I found that the consequences were very bad. But when there is another choice, he will still choose the same as before, because he wants to try again to see if he can succeed. This actually means "healing the scar and forgetting the pain".
When the scar heals, it really won't hurt any more, but the scar left on you is permanent. Although I can't feel the pain now, when I see the scar, I should think of what kind of pain I have experienced before. But many people can't do this, because they can't remember the lessons, so they will habitually repeat the same mistakes.
