The Dogs of Mumbai

So it's odd to spend even a few days in Mumbai and realize you haven't heard one angry shout, one crying baby, one annoyed huff. That when you placed your empty teacup in its saucer, three waiters rushed from different parts of the room to refill or replace it, without a single rolled eye or sarcastic murmur. How can this many people coexist in such circumstances without getting on each others' nerves? Where's the surliness, the road rage, the profanity?
All among these mild people are equally mild dogs. Well, animals that look very like dogs, but have no other doglike attributes that I could discern. Thin, limp, doe-eyed creatures. Mostly just standing or lying in one spot. Of various sizes, shades, and conformations, but all peculiarly similar in the face. Long, delicate faces, with sad expressions.
On Juhu Beach, at intervals, barrels have been placed for trash. In the shade of every barrel is a dog, curled up in a hole, lying very still. That's the pricey real estate, I guess. In between are many more dogs similarly situated, minus the spot of shade. What do they eat, I wonder? The millions of people are all so thin, it's hard to imagine they leave any edible bit for the dogs. Yet no animal barks, growls, or appears capable of the least aggression.
Conservation of energy, in the face of blistering heat and little nourriture? Or inscrutable Eastern wisdom, which extends to even the lowliest creatures?
