Driving home

It's odd how one's mind can totally take over sometimes. I've made the trip to my parents house more times then I can remember. Tonight driving home I had a lot on my mind. Things I need to do, things I need to get, lots of things. All of the sudden on the way home tonight I noticed I had missed a large portion of the drive home. Not miss as a wrong turn, but miss as in I don't remember driving it. My mind had taken the wheel and let my brain wonder around in my thoughts. I wasn't tired, It just happened.
