Today, while waving goodbye to my friends, I tried to lean into my car and open the driver door at the same time. The result was jamming the corner of the door into my forehead, where I now have a charming bruise starting. It's good enough that I can see my new Badge of Sensotard Honor in my shadow.
STEP ONE : Open door
STEP TWO : Lean and get into the car
NOTE TO SELF: For future references, do not try to do both at once. You are not John McClane of Die Hard fame.
