First of all, we should seriously consider the position of this friendship in our mind. If the position is very high, then no matter who is right or who is wrong, we need to take the initiative and be more active, which will give us more opportunities to make peace and show that we care about this friendship.
Find a time to have a good talk with each other. There are differences between people. Even among friends, they need to accommodate differences. Therefore, when conflicts arise, we should actively communicate with each other, talk with each other, and reach some consensus.
It's not terrible to find friends who know each other to help us to make peace. What's terrible is not to solve the contradiction, to find friends with each other, to face and deal with the contradiction together, a friend or a friend.
If the contradiction has already involved the issue of principle, you may as well give up such feelings. After all, people with different views are not suitable to be friends together. Even if the contradiction is solved now, there will be more and bigger contradictions in the future. It is better to let go earlier.
If the other party apologizes with itself or comes to find himself, then give the other party a step down, and also give himself a step down. We should find a way to manage our friendship that suits us, which will make us better and get more exercise.
It's not one's fault to express one's apology if one slaps his hand and doesn't clap. It's not one's fault to have a contradiction. So it's no fault to apologize first in the face of such a problem. Since one is destined to be a friend, the contradiction doesn't mean the end of this friendship.
