Something I do a lot reminded me of this post by opalcat. Who else does this? ... As I drive along the thruway and come to an overpass, if I see a car up on the bridge that looks like it would collide with me if we were on the same plane, I keep an eye on it and see how close we get, then if we do meet up I try to imagine the intensity of the collision.
Ok, maybe not as demented as OpalCat's imagination of tasting her dog's butthole, but still a bit weird. :)
