Oooooh!!
Trouble is, zebo, if your children are being bullied at school then it would be very unwise to go direct to the parts of the other child and going to the school is the best thing to do, because they can liaise with both parents and save some very tricky situations. Some parents do take it into their own hands and it makes the situation worse.
I think it was a well done storyline, in that originally the head was worried and didn't act appropriately because the child was the grandaughter of a governor - and, having worked in schools, I can assure you that this would be a tricky situation. In the end the Head was brought to his senses by his partner and acted correctly and tactfully and fortunately the governer involved was sensible.
