On my nightly trek home a little after 7 I had gotten on Central at Forrest as usual, and made it over to the fast lane just as they were shutting off the exits under 635 for . The traffic backed up pretty quick so I slowed to match, but I guess my mind was elsewhere because on the second or third "stop and go" I was coming up on this cars ass end a bit faster than expect. I slammed on the breaks immediatly, but the wheels locked up and I slid right into the car. More concerned with her's than mine I reached into the glove box to get my insurance, and by the time I exited my car she had looked at her bumper and was practically smiling. Thank god for 5mph bumpers! Not a stratch on either car so I apologized a few more times, we shook hands, and got back into our cars. This morning I found a patch of her car wax on my front end, but that's it. No more sleeping on the way home for me, that's for sure.
