This is a picture I did not take

of what I was thinking while reading the Diane Arbus biography on the train, specifically this passage; "She would photograph elderly twins and twins married to twins, and each picture seemed to ask what is it like to live in a body that is virtually indistinguishable from your twin's?" and when I finished the paragraph, I looked-up to see two men walking toward me, two men who were twins with Down's syndrome, both heavyset and each carrying a plastic bag (one had a map, the other a train schedule) and I slowly turned back to my book, blinking, as they settled-into their seats right across from me. (Photographed, months later, here.)
