Or adults!

I used to teach massage at a vocational school, and for multiple reasons had a "no phones" policy on the classroom (distraction, exposed body parts, and others.) I could have ignored it during lectures except that the overlap of students on their phone and the ones asking to re-explain information or just lost as to what they're supposed to be doing was nearly perfect.

I truly don't understand the college students who are paying insane tuition to be there to get a degree and they couldn't care less. I don't know if their parents are forcing them to go to college or what.
