Sometimes you don’t need to travel. I stepped out for a short walk to clear my head, and saw a tourist’s Mumbai spread out before me. Beyond the haze of Backbay were the high rises on Malabar hill. In the foreground, children from the slums had walked out on to the stones exposed by the tide. There are no parks or public spaces for some people; they exist only on what the city cannot take. This is a view of Mumbai which the tourist cannot help but notice, but it is a view one can lose track of in the middle of the daily routine.
