where i grew up if he didnt fight back in this situation he'd get a daily @ss beating. if you want to avoid charges make sure the fight is on private property ie your house his house etc. and make sure you both agree that its mutual combat, if your really paranoid have him sign a paper acknowledging it, and make sure your not 18 at the time if he is under 18. Best of luck one time some guy just punched me out of no where so i had to fight back otherwise my high school life woulda been ruined. Remember you can be the cool guy in high school with all the chicks, or you can graduate from ollege and get all the hot women with bigg h00ters
