On the metro, I notice a tiny, unusual looking old man, gnomish in appearance. My girlfriend tells me that he's been selling chewing gum and lighters on the metro for years. Apparently, he was pretty unpleasant if you weren't interested in buying anything, becoming loud and aggressive, shouting "Gracias, gracias, de las gracias no se come!" until people gave him money to leave them alone.
This particular night though, he seemed to have lost his fieriness, merely looking very old and sad.
