And then I heard the ring of metal on concrete, and I went cold, because one of them had found a piece of rebar lying around, and I knew with sudden certainty that these guys were going to kill me right here on this stupid sidewalk, for nothing, without even the reason of knowing my name or hating my politics. They were just going to kill me because they needed to kill something, and I was handy. At least zombies would have had a reason.
