This just in: writing fanfic is hard. Really very hard - think Douglas Adams intoning about how space is big. I'm sure writing generally is hard, too, but when you're out of practice? Yeah, draining and difficult and not a good match for a long work day. If this is the best I can do I'm not sure I deserve the title of fanfic writer, because actually being able to pull this off is a really noteworthy thing.
Here's hoping good intentions count a bit. Maybe when I'm less worn out I'll come back to it. For now, sleep.
