As I read on the bus about how China and India were going to take over the world by 2020, I noticed a distinct aroma coming from behind me. I thought it was a burger, or maybe a cheesesteak. At the next stop, the man who was sitting behind me moved up and joined me in the empty seat. He had a brown paper sack with him, and I saw him reach in, grab a handful of fries and stuff them in his mouth.
