They HIT YOU?!!
Okay, you know what. I'm gonna try to give you some self defense tips.
If someone tries to hit you, GRAB THEIR ARM QUICKLY, turn it around and press on their elbow. It will send them to the ground. Don't give any shits if you accidentally break their arm, you have EVERY RIGHT to defend yourself, and plus they are clearly asking to be hurt.
This is one of the reasons why I suggest Computer School.
