We had a real nasty mongrel magpie where I live, it would appear out of nowhere, as silent as Port Adelaide fans and it usually drew blood. It swooped on a very popular cycling route, which a mate and I used nearly everyday. So one day my mate says " I'm gonna take the back streets to get away from it", but I says " Nah, I'll go staight through", funny thing decides to follow him down the back streets, peck his ear and leaves me alone.....I nearly fell off my bike laughing when we met up a few blocks down the road.
