Might end up with a fight -

Well, on Thursday, we had a school dance right after school. And I wasn`t feeling too good. ( Sore throat ) My aunt usually drives us home now because of the snow. When they left, I found out I forgot my keys in my other jacket because I went to the dentist the other day and put my keys in there. And I had a cousin come to my house after school too. ( He came home with us ). So we walked back to school. As I was putting my stuff away, these grade 8 kids shoved me into my locker. I wasn`t too happy with that. I`m a freshman in grade 7. I didn`t get a clear look at the guy who shoved me, but I saw his friend laughing and I see him A LOT.
Earlier, about 15 minutes before school started ; I saw the friend that was laughing and I kicked him by the shin. He didn`t notice, but I`m planning to hurt him somehow. He doesn`t look too strong. Neither am I. But, I never got bullied like that before. I don`t get much attention by anyone. Maybe a few friends. I have a few tough friends at school too. But, I`m not going to ask them fight him for me. I don`t really mind getting suspended. Even though it`s my first time. I might get his attention by throwing a rock at his head first. ._. I have a habit of throwing rocks at things.
Any tips on fighting? o: Or a solution that will help me get a little revenge?
