Why can't real friendship be a joke in real life?

People's feelings are fragile. But it doesn't hurt to make a little joke, but it enhances the feelings. If you make a big joke, it's easy to hurt others and ruin your feelings. The same is true between parents and lovers. It's not that they are not hurt by jokes, but they just choose to bear it silently. When this negative emotion accumulates to the extreme and finally erupts, no emotion can bear this blow.

Therefore, I don't accept the saying that you can't make jokes in friendship. It must be that the other party was hurt by a joke and would choose to leave this relationship.
