PD- (And what does the DAR stand for?)
You're comment is pretty sensible bro! Always the Cannie's!
Was gonna say (but then you said it yourself) that if these school dude's really felt that way then they should have expressed exactly these comments to the parents in the way you put it. To hide behind H&S etc. is just typically weak and Burnsish (as in Mr Burns from the Simpsons) of the 'new' (weakened since WWII) British culture!
Now where can I go to rant about a nation who managed a quarter of the globe but has opened her legs to the EU to be governed in every matter from no longer being allowed to sell in lbs weight to what you should say in public!
