Although this isn't new - I've gotten this feeling, oh, every other day for the past week or so.
Which is slightly worrying in itself. Because that probably means I really am forgetting something. But I can't remember what it was. And no one has told me yet, which either means, a) it was an exam and uh... no, that can't be it, b) they're being nice, and it was a club thing that I forgot... or c) it was something personal, where... I'll remember a few weeks from today and invoke an "Oh Shit!" response.
