Who parks a motorcycle, with its keys in the ignition, on the sidewalk of a busy six-lane road? Someone. I don’t know who. But whoever you are, your black Yamaha bike was looking very lonely this morning when I ran by. I thought about borrowing it. Taking it for a spin through the nearby park, instead of running the seven miles I had planned. Fortunately for you dear bike owner, a joyride would do nothing to help my training for next month’s marathon. In fact, it could severely hinder it given that I don’t actually know how to ride a motorcycle…and you didn’t leave a helmet. I’m also not much for borrowing things without permission. So I continued on my way, speeding through the neighborhood with the wind in my hair.
