No, your not getting me here, in your happy place, there are no rules, only yours. in there, you can do stuff to him whatever you want, so you make fun of him inside and just grin at him, while he does not know what the hell you wish for him.
he
mocks me
walks up to me
purposely catches up to me
stares at me for far too long
annoys the absolute F**K out of me
oh, AND he tried to break the ONE THING I F**KING NEED FOR SCHOOL.
Those are a lot of reasons to go to your decan, teacher or tell it to your parents, they can call school and tell them about it, so they can take care of it.
Then, use turned pshycology, if he stares at you, you stare back until he quits.
if he mocks you, you laugh at him for that.
nothing physical, poking fun. and that should stop hi dead in his tracks i believe.
