my classmates concern me

i’m in a good school and a good class, we all get good grades and allat, but i have afew classmates who act like they’re still in kindergarten. slamming desks, throwing water bottles around, constantly making noises in class and talking constantly you name it

strictly abiding by the rules is obviously pretty lame but this is actually weird. i’m not gonna make assumptions, idk what’s going on in their personal lives, i’m just saying it noticeably sticks out and is kind of concerning
