I just changed mine! For the first time in, um... a very long time. My new signature is:
It's funny. You see great writing, I see a rest stop in Ohio...
It's from a conversation I just had with Beauregard, actually. We were discussing the chapter of fanfiction I just posted. He pointed out a line, and instead of thinking of the line itself, I thought of where I was when I wrote it. That tends to happen a lot with my writing- when I re-read it, I think of where I was when I wrote it, what position I was sitting in, who (if anyone) was with me... So I thought I'd throw it into my signature. I've been meaning to change it for a while now, anyway.
