1. Place your sleeping bag and roll mat (essential) with your head next to a wall (You won't get kicked in the head that way). If you are there early, other people will follow suit and hopefully leave a space for loo-runs.
2. ALWAYS kick inconsiderate people who sieze corridoors as their own personal dormitories, thus blocking off entrances/exits. They will get the message, move, and the world will be a nicer place.
3. Giggle loudly when people fart & snore. It is school, after all, and there are certain conventions that need upholding.
