Oh... the worst thing that happened at my high school... guy got stabbed while trying to stop a fight and some guy falling through the roof while tagging with a girl =.=
Your high school has a cafeteria, right Samkaka? Maybe oil got accidentally spilled on the floor and a spark fell into the oil causing the cafeteria to burst into flames.
I like my high school too... They separate the freshman and annex them in one building only to come out if they have classes or lunch in the upperclassmen building.
