GBZ, I became a teacher when I left the mob and one of my headmasters was a stickler for correct uniform. He would pounce on a minor misdemeanour such as having the wrong colour socks. I once asked him why he was so keen about enforcing school uniform policy. 'Because if you win the battle of the socks you don't have to fight the battle of the shirt or shoes' he replied. I learned a lot from that guy.
