Troll

In a backwater of my mind there is a rickety bridge.  Underneath the bridge there lives a miserable troll.  The troll despises most everything, including himself.  Sometimes the troll has some valid points to make about the world, but even a miserable troll, like a broken clock, is right twice a day.  The troll probably would be less miserable if he lived somewhere other than underneath a rickety backwater bridge.  He's a troll, though.  That's where trolls live.
