August. Daytime temperatures in the city routinely reach the mid to high thirties. Outside, heat radiates from pavements, buildings, car engines and the exhausts from air conditioning units; it feels hotter still. Outside the air is heavy and it seems you could melt. Unsurprisingly people seek refuge. Seek shade. Head inside, to shopping malls, department stores, indoor plazas, covered passageways. Inside, where the sun is blocked and those heat-expelling air conditioning units work their magic to chill the air, where one can recover a sense of equilibrium.
