Spaaaaaaaaaaaaaaaaace Cadet

Yet another award-winning conversation with my anatomy instructor (whose class I missed on Monday) upon bumping into her at the bookstore yesterday:

ME: Oh, hey, Dr. ____. Sorry I missed your class yesterday. I got a flat tire.

INSTRUCTOR: That's ok. The secretary gave me the message you left with her yesterday.

ME: Oh, good, I'm glad. Yeah, by the time I managed to get the tire all fixed, I had already missed most of the class so I figured it wouldn't be worth driving all the way out.

INSTRUCTOR (long pause): That was last week, yes?

ME: Uh, no. That was yesterday.

INSTRUCTOR: Oh. Ok.

*long lingering uncomfortable confused silence*
