I know I have a problem paying attention to ANYTHING for a long period of time. (Insert obligatory "look squirrel" reference here.) I'm also very aware of my ability to daydream about nerdy, geeky, or just plain weird random things in the midst of "normal" activities. Driving home last night after a LONG day at work I managed to impress myself with my level of all of the above.
I discovered that if you drive in the middle of two lanes it kinda looks like your car is Pac-Man and is eating up the lines on the road.
