When I was a child, I had a friend in the neighborhood. A smart (and slightly nerdy) kid, not unlike myself. We used to hang out, play badminton and do physics experiments. By the time we were teenagers, we kind of drifted apart, as our paths diverged. बाद में, I went the IIT-USA, global-citizen-route and ended up in Singapore. He, of more modest ambitions, stayed back at home, and got a job roughly similar to what my father used to do. I kept hearing of him, although I never really ran into him. He got married, probably had a couple of kids, and everything must have been going smoothly, even a bit dully. But a couple of years ago he suddenly died of leukemia.
