Was walking in the library when I stumbled on this sitting on the floor outside a classroom.
I had to do a double take to realize it wasn’t random litter. On the back:
Well that was nice! I’m not sure of the original intention of the note leaver, had they placed it there on the ground or if it accidentally made its way there, but being an old hand at hiding notes I decided to move it elsewhere.
Hopefully someone that needs it finds it!
