It's harsh that this had to be labelled as being "expelled". It sounds like he may be a handful, perhaps he's just not ready for school? Couldn't they just say, keep him at home for another year, he's clearly not mature enough - has he been to nursery? What were their experiences of him and should they have not picked up on his behaviour there? IF there were bigger issues at nursery shouldn't they have drafted in some support then in the form of an Ed Psych?
It just sounds like there are crucial pieces of this story missing. And is that HIS photo? Strange if it is. It's all a bit cheeky chappy isn't it when that definitely is not the case because his life is stuffed if no-one wants to educate him.
