Gum

Yes, gum. There are a bunch of old study carrels in the ground floor hallway, presumably on their way to surplus. The bottoms of almost all of them are plastered with fossilized gum. God only knows how old it is. It’s been a long time since chewing gum was “not allowed,” so I’m assuming kids don’t have the same incentive to hide it under their desks and chairs these days. Maybe I’m wrong, but the “newer” chairs that are also on the way out do not have gum stuck to undersides of the seats.
