Do you ever find yourself driving somewhere and end up someplace else?
Like this morning - I decide I'm going to stop by my favorite coffee place on the way in to work which requires a slightly different route. But then my mind starts its usual strange pattern of random thoughts. When I come to, I see that I've just followed my regular route in with the coffee place no where in sight.
Subconscious driving. I guess the lesson is not to drive near me in the mornings. At least until I get my coffee.
