I think there's a homeless girl that lives at the library here. Every single time I've come here, without exception, her stuff is at the same table in the same place. Sometimes she's at the table, often she's not. Almost everytime that I've seen her at the table she's sleeping.
But her shit is always there, and always in the same place, for over a month now! I just looked at the page number her book is open to and it's on page 64, over the next couple days I'm gonna check to see if that ever changes.
Here's a picture for posterity, let's see if there's anythig different over the next couple days/weeks!
