Typical? 40 years ago, when I was your age, we never dreamed of misusing a piece of emergency equipment! That was in the same league with setting off a false fire alarm: it just wasn't done.
Besides, it would have resulted in a suspension.
High school IS "Big Boy and Girl" school. College is "Young Men and Women school."
Most high school seniors are LEGALLY ADULTS when they graduate, and should act like it. For many of the grads, it is the last time they will set foot in a class room.
For Poser's sake, I wish more would get a job, rather than waste their time and everyone's money on 'higher education' with a major in keggers, and minor in video gaming. He wouldn't be forced to toss so many out, and those wanting to learn would have an easier time doing so.
If you were indulging in such behavior as you describe, I can only shudder to imagine what the your Liberal classmates were doing!
