This isn't quite a commuting story but I'll tell it anyway.
I try to do a quick mile jaunt on my lunch break in order to get in some exercise. Well, I'm coming back to work from that when I see a woman walking ahead of me. A guy is following her across the street and all of a sudden closes the gap on her and smacks her in the head (ah love, Pueblo style). The guy then walks a bit up the street away from her then starts following her when she starts going down another street. Just so much that you see from a bicycle if you actually take notice.
