Flippancy is great - it is our inbuilt and natural coping mechanism in a world that frequently presents us with events beyond our ability to manage, thereby allowing us to retain our sanity. But, sometimes, we need to take a step back and allow ourselves to realise the full severity of them.
After today's tragedies, shouldn't we be talking about ways to stop death, rather than joking about ways to cause it?
(Semi-caveat: I don't mean to sound like a harbinger of doom and gloom. It's just that I have two beautiful girls in the room above my head, and as a result I feel so deeply for those who have suffered the ultimate tragedy today)
But it does move! -- Galileo Galilei
