Did you see the hawk over the High Line, or did we imagine it?

On a Saturday afternoon on the High Line, a crowd of us stopped walking at the same time and looked up, the way people do when a hawk is circling. Nobody said a word. The hawk dropped over the railing and everyone began walking again, slightly different. A man next to me said, did that happen? I said, I think so. He said, good. We kept walking in the same direction for two blocks without discussing it. I have not seen the hawk since but I look up on that stretch every Saturday.
