generally, i'd say beat the living shit out of him/them, but i dont want you to lose your job. i get the same shit by a number of other "bodybuilders" at school (and by fags in general). it happened today too i might like to add (and this day, for my own personal reasons was a very bad day, i was on edge and was clearly not in the mood for taking shit..so what happened today? some punk called me a name from the safety of his classroom, through a window. well he was mistaken about the safety bit. i stopped dead in my tracks, looked him dead in the eye, marched towards the dorr, then threw the door open, marched in, ripped him up outa his chair and slapped him across the face a few times, in front of his mates and whole class. he was scared shitless, himiliated, embarrased, and nearly pissed himself for real.)
anyway, generally i would not have gotten away with that but under the curcumstances (eg: the personal home issue i have atm) i did.
sometimes u can get away with shit. but dont take the risk when it comes to employment. if he's calling you small or w.e just say something sarcastic like "yeh im really patheticly weak.. i need to bench ur mum more, how bout i superset ur mum with ur sister" something like that, u get the drift
if ur working with and around girls when this happens, do it with confidence. they'll love that and it will make him look like a wanker in front of them, which will damage his ego and resolve a tad more.
sarcasm is how i deal with shitheads when the conventional method is not an option. you could give it a try? |
