@AlphaDoti - just to lend to what Obi Wan has said....on enrolment you DID pay something called caution fee? That money is meant to cover any damages occassioned by your son - now they have collected such from all the school kids and upon exit from the school,should there be no loss to property (books,window panes,chairs,etc and anything that can be damaged,the caution money is refunded - I recall looking forward to that 'boom' in high school). So I think the school shoud pay for it. If the kids were playing together,it should be born by the school as much as if kids wee playing foot ball and broke a window. Don't let them foist it on you - its their premises,if its private,there should be some form of insurance...
The problem with equality is that we desire that it be with those that have more than us rather that those that have less
