So I stripped off my blazer and my tie, and went to wait for the bus home.
I hadn’t yet learned about the intelligence network the school ran.
Old boys from the school tend to remain associated with it, and also tend to value its standards – and if they see a boy from the school letting the side down they are likely to phone the school.
I’ve done it twice myself this year actually.
You might even phone one of the other similar schools if you think the behavior of their students is bad enough.
Then you add in members of the general public who like phoning the schools to complain about their boys…
well, basically a lot of the things that happened outside the school came to the school’s attention.
And somebody saw me.
And somebody phoned the school.
