The Smallest Thing Has Derailed My Day

I've been corresponding with a professor by e-mail for a little bit, and today I got an e-mail back from her saying that it was nice to see me the other day. The thing is, I don't think I saw her "the other day" or, really, for months, so  it made me wonder who she thinks I am.

Not in a snarky "WHO DOES SHE THINK SHE'S DEALING WITH?!" kind of way, but in a seriously confused who does she think I am? Who does she think she's been talking to this entire time?

It's possible that I did see her at some point in time and just don't remember. Since starting graduate school my memory retention has decreased to that of a new puppy or goldfish. But I strongly suspect that this isn't the case. I strongly suspect that she just, genuinely, doesn't know who I am.

**sigh**

It made me feel forgettable, and that made me sad.
