—One New Delhi morning some years ago, before there was much traffic, I went for a run. I thought I’d go 5 kilometers (3 miles) and then, to avoid getting lost, return along the same route. But wild dogs thwarted my plan. Rulers of the side streets at 6 a.m., they recognized me as a visitor right away. At one point, several were chasing me, barking and rallying their canine friends. No problem going past them the first time – I simply ran faster.
