You know that feeling where you get to work and park, then think back and wonder, did I stop at that last stop sign? You were lost in thought, moving through a routine know so well, and then you turn off your autopilot and think, do I have shoes on? That happens to me a lot, especially on Mondays. Only now it's routines different from driving. I'll be in the shower at the gym after not having seen anyone else in the locker room and think, "Did I go into the women's locker room by mistake?" And when I'm pedaling my bike to work, I'll look down after the first four blocks to make sure that I remember to put on matching shoes. So far there have been no catastrophes, though there have been several instances where I've forgotten to wash the conditioner out of my hair.
