His story was that he was in his last week of school befor leaving to start his new job and he decided to set off the school fire alarm system, just for a laugh thinking that he would not be found out and that even if he were he would be gone by then. However, he was found out, I cant remember how and summoned to the headmasters office at the end of the afternoon on his last day of schooling.
The headmaster lectured to him about putting peoples lives at risk through false alarms etc. etc. and that he had earned 12 of the best but since school rules only allowed a maxium of 6 he would have 6 now then would have to call back into school after work in a weeks time to have the last 6.
