Classrooms are a zoo now. I am not that old. But a couple decades ago, my school banned "beepers". Yeah it's an ancient device. But their explanation was that usually the beeper would prompt you too get in touch with your "dealer" so that why they were banned on campus. Anyone with a beeper will get a suspension.
If you know what a beeper is, yeah you are that old lol.
Frankly, when I went back to school awhile, above-age girls would send almost any pic to you of themselves.
The ratio of women in schools vs men now means the guys get to pick freely nearly. I just missed that wave!
