I've broken up a couple of fights myself. chair throwing, slipper slapping, tae kwon do. But yeah I am also interested in knowing if you would have stopped the girl if she was hitting a boy. Not always are the boys in the wrong.
its natural for a boy to tease the girl he likes. but yeah, just watch out for verbal cues and facial expressions from students. i usually find that the girls provoke the boys publicly to their friends and they all laugh together. so sometimes u have to talk to that one individual.
alot of their games involve pain such as, kawi bawi bo, the losing soccer team get the ball kicked at them, flicking, etc. they all go to tae kwon do, their chant is "fighting" - i think its alot deeper than just the class room as well.
i will stop rambling cause even i dont know wat im saying
