No, it's not too bad, really, I volunteered to cover this shift. Because for one, it gives me a chance to catch up on my work in a quiet library, do all the stuff that slipped while I was gone. And for another, I get to take next Friday off. Working seven hours on a Saturday in exchange for a three-day weekend? Yeah, I'll take it.
Still, are there things I would rather be doing on a beautiful Saturday afternoon? Without a doubt.
