For a short time, there was a young woman living in our neighborhood who had two heads. I'd see her (them?) walking her (their?) dog. I had seen this before in infants, many years ago, when I toured a state hospital back east as a part of a psychology class. But it was something else to see an independent young woman with this condition out on the street. We didn't speak. (I typically don't speak to people on the street anyway.) I tried not to be "weirded out". But it was certainly unusual.
