This story has a strange ending. I have never ridden in a car to or from this office even though I've had the job almost 2 years. However, I will accept a ride home tonight from my wife.
It has nothing to do with forgetting my helmet -- I still intend to buy a new one today. My wife is going out with some friends of mine after work, and they want me to join them at a bar that's barely a mile away. My commute is on a fairly busy 2 lane highway, so it would be suicidal to drink anything and ride home in the dark and the rain.
I've never let the weather beat me, and I swore that the first time I wussed out, it would be for a worthy cause. This qualifies.
