DAE hit a weird haircut milestone and get caught off guard by it?

I was sweeping up after a walk-in on a slow Wednesday and counted the heads I've cut at this chair since I started renting it in March. The number came out to 1,000 exactly, which kind of spooked me because I wasn't even trying to keep track. What got me was thinking about the guy who sat down at about number 400 and told me his kid was graduating that weekend. I've done 600 heads since then and couldn't tell you half their names. Funny thing is I remember almost every bad fade better than the clean ones, especially a 1 guard on a guy who wanted a 2 and swore he said 2. Anybody else keep a rough count, or do you just let it pile up and not think about it?
