I had hit a boy in my school.

You do something that really hurt him, right? Maybe you shall say "sorry" to him first. Actually, I know you have already do this step, but I have to make sure you do so. If don't, please tell him as quick as you can.

I think you shall find a chance to talk with him. You may ask him to give you two or three minutes for you to explain. You shall tell him that you are soory about that and you don't want this happen. You should also tell him that you are upset and this is an accident.

As that worse thing could happen, he will only tell the class teacher and the class teacher will punish you very hard. I don't really think that he could make the principal to kick you out of that school. This seldom happens in Hong Kong. No principal would kick their students out of the school. I am quite sure about this, trust me.

If the boy tell your class teacher, your mom will know obout it cause your class teacher will tell her. If you find out that the boy tell your class teacher, you better tell your mom as quick as you can. You have to make your mom to trust you so that she will be your back up.

I don't know if you is fight with the boy or just hit him a bit like having fun. If you've just hit him a bit, I think he is kidding, that he is not going to take any actions. Or he takes action, the things will not be that awful like what you think. Otherwise, if you fight with him, or hit him very very very hard, you will be punish very hard too.

So,,,
GOOD LUCK, little girl.
Never do this again, remember.

It's been some time, right? So, if he wanted to tell anybody, he might have already done so; if not, he might not be really serious. You might also sincerely say sorry if you haven't done so before, or just simply try resume speaking naturally, and don't make it a scene for yourself . Also choose the right time to tell your mom, but don't make it like a big deal until it becomes a big deal. That's what you can do. Don't write anything to the boy, which might end up something come back to haunt you.

Maybe the boy was just trying to make you feel threatened, he might not be serious. The bottom line is, don't do it again!

I I think you can say sorry to him. you can write a sorry letter or card to him. If you express you apologize seriously, he will feel that and forgive you. Don't worry about that.

Frist , you can say sorry to the boy
Then , you can explain why u hit he , so that maybe he will forgive you
