Heres my advice you might be scared of him but that might come in handy cause once you start hitting him youll be to scared to stop so just hit him hard and fast it will stun him and just keep hitting as fast as you can dont worry about perfecting you your technique in this fight and most fights in school dont last for more than a minute or if you dont want to fight then just go crazy and flip out screaming at him as loud as can scream cuss words and stuff then he might chicken out ive seen it happen alot, my friend has dodged a couple fights that way
