Ouch <(. How did that happen?.
I was riding my bike up a hill in the dark and I didn't notice that the already extremely narrow sidewalk suddenly narrowed even more. My wheel scraped along the curb and the whole bike tipped over. To my credit, the bike never hit the ground and I was back up and riding within seconds. It wasn't until I got indoors that I even noticed my leg and elbow had scraped across the pavement >____<
