Critical Mass London: last friday of the month South Bank by National Theatre, 6.30pm

Girlfriend is out, as she is having drinks with the rest of the teachers after school (I've never seen such drunkeness as them, teachers should know better!)

From my time as a teaching assistant, I can vouch for teachers being pretty hardcore drinkers. The best is junior school teachers... those kids can't tell the difference between a hangover and "that headache that adults seem to get very often".
