It rained briefly but heavily in the city at lunch time yesterday. The sun came out almost immediately and the sky was predominantly blue again. I was sitting under cover of what used to be the Bank of Queensland building. As I walked out towards Elizabeth Street, a light rain was still falling. On the footpath, I looked around for the source. Only blue, and a few flimsy scraps of cloud. On the open space at the end of the Mall, as I headed down Edward, a light sparse shower was still falling. I looked up into it, and saw tiny balls of water falling towards me, drifting sideways in the breeze. Then it occurred to me that this must have been the runoff from the hi-rise. Up above, from pools on the top and from window seals and edgings, from concrete awnings and the various nooks and crannies on the face of these towers, residual rivulets were making their way to some precipice. Falling, they were being flailed by gravity and the wind into a spray of droplets, to make their their individual and scattered way to the street, like an afterthought of the shower.
