i'd get extremely annoyed if a guy fell asleep on my shoulder on the train or bus. usually i'd bang his knee or tap him.
but i wouldn't mind if it was a girl... though it has never happened before. heheh...
for me it wasn't primary school but secondary school. some guy would be pooing when all of a sudden, the cubicle door would be kicked open. and that bloke would be humiliated for months to come.
good memories though. :)
