My best friend, we don't usually make much noise, but today she hurt me in front of many people and was joking. Then I hit her back, maybe my tone was

There is a saying that hitting people does not hit them in the face, and revealing people does not reveal shortcomings. Maybe when she hurts you, she hurts your self-esteem. I can see that you are very proud in front of everyone. You also hurt her self-esteem when you retorted, not to mention how deep you dug when you were sarcastic.

You said that you two are best friends and you can talk about everything. You can make fun of it at will, but after all, leave your feelings and space in front of outsiders. You can't say everything. Maybe you are hurting each other out of an unintentional sentence.

Everyone loves face. But I don't want to pretend like you think. This is a little heavy. It shouldn't be for your best friend. In order to ease the atmosphere between you two, I suggest you talk to her and tell her your mistakes first, so that the other party will look at you with new eyes. If you take a step back, of course she will blame herself. After all, it takes a slap in the face to hurt you first. Come back and explain why. I believe you are reasonable people, and your friendship will be stronger.
