Defend yourself(Try to block), Tell them logically what they are doing is completely useless and he/she is just letting their emotions make them perform useless actions Seriously they are just doing it to make themselves feel more powerful and feel better about their shitty life
what u need to do is to make an egg to get rotten then break it inside his bag/ throw it on him. or u can just put inside his bag oil then he will have to pay mony on the books that got dammeged
Just hit him back. You're seen as a wuss if you don't. If he necks you, tell him to stop. If he does it again, tell him again. If he necks you a third time, throw a closed-fist punch at the point where the jaw connects to the neck. That will give his brain a good shake, possibly even causing him to go KO for a moment or two. After that, he won't neck you again. Ever.
