So I've just spend 3 hours in an exam in a different school.
I wander outside then realize I have no idea where I am.
Then I finally get back to school and the door's locked. And since I'd just been to an exam all I had on me was an admission slip, a pen with Judai on it and half a box of mints, everything else was locked inside.
So I had to stand outside and yell until someone let me in.

Good times.
