I can attest after 34 years experience as a teacher that
some 14 year old CHILDREN are thoughtless,careless and do some really stupid things.To blame them for it is a waste of time as they ARE still children and still have a lot of learning to do if they are to survive until adulthood.
Of course some never do learn and regretfully we have to hope that they never have any children in that case...
Of course the majority of children of that school now do have a rather more advanced idea of what is a dangerous and avoidable action..I suspect it's something that WON'T be repeated anytime soon...
Sometimes a member of the herd has to take one for the herd to advance as a brighter leaner SMARTER herd together.
