It's a Solomon's baby thing really isn't it? If they were good parents who cared about their child's education even if they were really annoyed and angry about it they wouldn't have behaved the way they did.
They could have taken it up with the council or governers calmly, organized other parents to object and campaign for the rules to be relaxed in a non-aggressive way such as a petition. But going in and shouting the odds and threatening to send the kid in with nothing so he starved was awful.
They must have known that the main person who would be hurt by this was their son by being caught up in the middle of a battle between his school and his parents in a battle.
I mean, come on, is it really worth risking your kids education over a packet of mini cheddars?
The family's name is going to be mud in every school in the area, and wherever this boy goes now he is going to carry a stigma and the teachers are going to be keeping a very close eye on him.
I can understand why they find it annoying, but I don't believe good parents would have behaved the way they did, dragging their poor child through the press and effing and jeffing in the school just because they want to prove a point.
Basically proving a point was more important to them than their kids welfare. None of this will have done him any good and they didn't put him first.
