Cosima knew that, which made it better somehow. Like the fact that she acknowledged it was weird doing it somehow lessened the weirdness, like it wasn't totally strange to sneak into the library to leave post-its at the table where the cute French girl always sat.
She liked to think that most of the decisions she made were good ones, or at least one that wouldn't doom her to a life of cheap potted cacti because she couldn't take care of a hoard of cats. She liked to think, even, that one of these decisions would prove brilliant, that maybe post-its on a table were a surefire way to love and success and great stories to tell her grandchildren and/or potted plants someday.
So with that inspirational idea in mind, Cosima let the library door close ungracefully behind her. Sneaky wasn't her thing, and her boots clomped loudly on the tile floor. But the table wasn't all too far away, and she noticed happily that no one was there. So into her pocket she dug, pulling out a pack of post-it notes and a bright red sharpie. She wrote slowly, oddly thoughtfully, and left five post-its scattered across the edge of the table.
Hey you. (Not you. Her. Yeah, you.)
Welcome back!
Not to be super stalker, but I noticed you
flipping around a whole lot the other day.
Try appendix A. It's got all the formulas he
kinda seemed to forget to tell us in class.
Professors. Gotta love them, amirite?
She darted away, taking a seat at her normal table a few yard away, and opened her book. Because she was totally going to get reading done--might as well pretend, Cosima figured. She had done what she came to do.
