Blech, I hate assemblies. Being a boys-only school, they're all about sports, which I have less than no interest in. So I half-listen to what national competition we won this week, and half try not to punch the guys behind me. People have an odd habit of untucking the shirt of the guy in front of them in assembly, which is helped by the slot in the back of the chair. It's a pain in the ass.
I also occasionally stand up to get awards. But that's only on the rare occasions we have assemblies focusing on academic achievement instead of bashing skulls on the rugby field. And when I say rare, I mean about three times a year. Lor'.
