Ach: when I wrote last night that I felt today would be a day I'd be "on," I forgot that crucial maxim: be careful what you wish for. First things were fine; then they weren't. They weren't not-fine in any kind of horrific way, just in the slow grind of useless annoyance, the sources of which are largely under control (at least to the extent that they can be).
Though, to be sure, I want to give you every detail of the things that went awry today, there's just no need to go through it all again. Instead, I will say that today was one of those days that made me want a macro lens--for all this greenness, for all these small things.
