No, don't kick them. If you do, both of you might get in trouble. I should know because I got into a fight once. Just tell a teacher! Believe me, you may think that that is weak but, the principal will take care of him and give him horrible consequences. I hope this helps. Btw, you may be worried that they'll keep on doing that to you even after you tell on them but, most bullies will be scared that you'll tell on them again.
