I was walking around the city the other day, headphones on, rocking out. I’d just crossed the street, and took a step to the left off of the curb, getting ready to turn left and immediately cross another street. I heard a squeal (which in retrospect was the sound of bike brakes on the rims) and felt a thud against my left shoulder. Before I knew what was happening, I saw a guy smack onto the pavement in front of me. I’d just blindly walked in front of a cyclist riding in the road next to the curb, knocking him to the ground.
