That’s why I keep a small camera in my backpack! Somehow the focus of our bathroom stall conversation (which hat started before I first came to our university) switched from conspiracy theories and politics to life advise (both serious and not so serious) and other randomness … the last two lines once read “me no cry / me go marry another guy” before someone removed the piece of tape the first words had been written on. I like trains, too.

That is great, such a good idea! :,)
Our university is full of little corners like this one – obviously students enjoy communicating via writing on all kinds of surfaces.
