I walked by a motorcycle repair shop in Thiruvannamalai. They were burning tires off of rims out in front. There were a couple kids tearing a motor down and keeping warm by the fire, they were between 10 and 12. I asked what they were working on and they showed me a transmission gear with a tooth sheared off. One of them said, "One pen?"
"Sorry I don't have any pens" I said. He smiled at me with gleaming white teeth against his dark and sooty skin.
"Does that happen often?"
"Yes," he said, "the metal is bad."
I smiled back and continued walking into town for lunch.
