I agree with DancingLedge who said it's a prison walk. Outrageous.
Why do you have to walk in silence unless it's in a solemn ceremony or you are being punished? I don't think it's a great idea to impose that in prisons either but as I've never been in one I'll confine myself to school, where I have.
The more I hear, the more I appreciate my headteacher and his staff. My secondary was a big school and the first years were let out 20 minutes' early in the first term to give them a head start to the station because the head sensibly realised that little 11-year-olds from small primaries would be overwhelmed by hulking teenagers.
But in the new year, everyone was expected to cope with leaving together and as far as I know they did. That was because we all mixed in classroom changes. There was a tower block of five floors with two wide staircases - blue for up, green for down - and though I suppose it must have happened, I don't remember anyone deliberately taking the wrong staircase. Not because all the pupils were angels, but because you couldn't fight against the tide.
Shockingly, we were allowed to talk and there were no rules on where we put our hands (unless they were on other people, but the head didn't feel the need to spell that out) while transferring between classes.
The only rules were that you didn't run - generally not possible - and that the big sports bags that some boys liked to carry could not be slung over the shoulder because you could bash someone's face in a crowd.
It was definitely noisy but what's wrong with that as long as pupils are quiet in lessons? Writing that makes me realise that we could have a five-minute changeover where we could all jabber like mad and then get down to learning. He was pretty sensible, that head.
