When I was in high school, someone had the bright idea to install doors to bathroom stalls made out of something like strong paper, not sure what exactly it was but it was made out of two large sheets with honey-patterned support inside.
You'd think it would be fine, but the reason I know what was inside is because someone tore holes into three of the four doors within weeks, and they only kept growing for a month or two (one got to about half a meter width at some point). Then one door disappeared, and some time later that same semester they put regular doors in.
You know, in regards to stupid things you'd never think someone could do. Some people can get disgusting under the pretense of having fun or messing around when they know no one can hold them accountable.
Hee how so? I simply judged from the comments but in my school there were specific people to check the bags of the students randomly on any day to see if we are carrying something like sketch pens or markers if it's not a art class day
