A bunny ran into my front wheel on the bike path in Pittsburgh. All I felt was my front end suddenly jerk, and when I looked back the bunny was flopping pathetically on the ground. I really wanted to help the little guy, but had no idea what to do (I figured putting an injured bunny in my messenger bag would be a really bad idea). So I could only watch as he half-limped, half tripped over himself to get back to the bushes.
It made me sad
