Teardrops to make you weep

The heatwave continues unabated, as merciless as Ming, causing the inhabitants of this 'burb to behave oddly. Latterly, I have witnessed... The same flustered woman being rude to then apologising to staff at the post office and the supermarket. A guy tinkling the ivories of an old upright piano on the footpath (presumably, it was there for collection). And a second dude, realising it wasn't getting any less stinking hot, cutting his lawn in a rush at about 8pm. If he'd waited until it was properly dark and worn a miner's helmet with lamp, this posting would've been 7000% more interesting.
