As the cold was on its way out, I may have caught the crazy in a writing project related sort of way, though. We'll see. It's good to have friends in different parts of one's life to whom one can say, "Have I completely lost it, or...?"
In the meantime, I didn't actually schedule my weekend with the idea that it should be the optimal intersection of fun and low-key (and possible with the vertigo, sigh), but it looks remarkably similar to that ideal anyway. Definitely a good thing.
