She should press charges. That's what parents are for. If they don't protect their children from kids like you , who will? Good luck and tell your parents RIGHT NOW what happened. They may need to hire a lawyer for you.
well most likely a mom is not going to press charges u have to be careful though because schools are now able to pin students on fights that happen after school. You are too young for jail and i highly doubt they would send you to juvy but why do u wanna fight the boy and is it worth getting in trouble at school for?
think before you act. Let's just say if he attacked you and you fought back, that would not land you in any trouble since that would be considered self defense. But if you started it and seriously hurt anybody, you could end up in major trouble with the law.
Assuming you live in the US, once something has been reported, it would be up to the prosecutor to go forward with the charges. The prosecutor might not want to pursue the case if there's possible evidence the fight was mutual, in that the other kid participated, or they feel it's just not worth pursuing. If the prosecutor does pursue the case, you would probably have to go to a juvenile court and deal with it there unless you and your parents came to some agreement with the prosecutor's office.
