Fire? (Part 3)

Guess what guys, ANOTEHR FIRE ALARM WENT OFF. This time we know it was an alarm pull, one of the freshmen during lunch go a little cheeky and pulled the alarm, causing everyone to evacuate. For some background info: Freshman and upperclassmen lunches are split into two different hours. So while upperclassman are at lunch, freshman are in class, vise versa. Anyways, as I'm sitting in my 5th hour class, just back from lunch, My history teacher starts to have this deep and meaningful convo with us when BAM...The alarm went off. We go outside, stay out there, then finally go back in. not even 5 minutes into being back inside BAM, the alarm goes off again for a split second before turning off. 

All in all, my school is really trigger happy with their fire alarms.
