hmm....I was actually a house captain in school. I don't honestly remember what the "Houses" were supposed to represent...although I believe there was some kind of point system in place, and whichever house had the most points at the end of each month got a prize of some sort. I can't honestly remember the details.
Anyway, I was head of House Tannahill for most of my time in the school, including when I was in Primary 7 (the last year in primary school)...which actually made me really proud, as it means I was the head, head, rather than just my year head...but anyway, I digress...part of my additional duties as a result was being "school messenger". I was required to deliver lettings, school news bullitens, and so on and so forth to every class in the school. A disruption if nothing else, as it meant I had to leave class to do it. But anyway...
When doing my rounds, I'd often find classes wouldn't be in...usually off to the PE hall. This would actually be very frustrating, as it meant I'd just have to leave the letters to be handed out on their desk, and hope the teachers saw it when they came back. On one occassion, I was becoming increasingly frustrated with the number of classes that were empty and, at one point, walked in to one class that was empty save for a single person who was apparantly there on detention.
I looked around the room, sighed, and said to the person "Are all the teachers on holiday today or something?"
Too late did I realise there was actually a teacher in the room, hidden from my veiw by a cuboard

She was not impressed with my sarcasm, and gave me a chewing out for it

The Sera One was very embarassed.
