my school has fire drills oftenly
sometimes they even have them when its like 20 degrees outside
also, sometimes we have "code red" drills, which are used if someone breaks into the school with a gun or something.
and we get an announcement "code red" and we have to all sit against the front of the classroom crushed together and the teacher closes all the blinds. There are also door blinds in which he/she closes, because the doors have small windows.
Also, we have electronic bells, which aren't regular bells. They sound like long beeps. And sometimes either it glitches or the controller presses an incorrect button, and it plays a sound like "boooo, BEEEP" and it goes on for like 8 seconds".
