A headteacher here in London was fired a while back because he expected the kids in class to stand up when he entered the classroom.
This blew my mind. When I was at school, I had to have my shoes polished, my shirt tucked in, my tie done up, and when the bell went, we had to line up outside the classroom against a wall and await inspection. If your shit wasn't up to standard, you weren't coming in. Upon entering the classroom we'd have to stand at our desks, behind our chairs and wait until our teacher greeted us. Only then did we greet him or her and then he or she would allow us to be seated.
Those were the days. None of this bullshit that kids get away with now. Don't get me wrong, I was still a naughty fucker and took the piss at every opportunity, but at least we learned respect. If only when the teachers were looking.
Kids nowadays have more power than the teachers do. It's fucking ridiculous.
