I looked up and saw a guy in the street had just fallen, presumably by slipping on the iced over road. Three concerned passers-by rushed over to help the guy up; he looked completely stunned in the face and held his own arm gingerly as if it or his wrist was broken. I continued walking because there were plenty of others to assist, but this was kinda scary.
Then another guy came riding up on his stupid hipster no-brake fixie and, upon reaching the same patch of ice, lost control of his bicycle and slid to the ground. I continued walking because he popped back up to his feet as if nothing happened, but this was kinda funny.
Still without breaking stride, I turned my head forward and saw at the end of the street a girl on a bike careening sideways toward the curb and slowly, eventually, to the ground. This was just sad.
