Darren,
Sorry to hear about you daughter’s situation.
I understand your frustration and theory about the parents possibly being responsible for their son’s behaviour. Obviously the kid has a big problem which he thinks will be solved by making the lives of others a misery.
Maybe someone like Derek can offer some assistance – using darkside methods of course.
I dearly hope the problem is resolved for everyone’s sake because school can be enough of challenge without this sort of activity complicating matters.
Perhaps you could take the kid under your wing and get him to test the sharpness of your blades – you always pull a chisel towards you don’t you?
