"And I think at the end of the day, that's all anyone is going to really care about."

Albert Camus, from a letter to María Casares featured in Correspondance, 1944-1959

The ground beneath our feet is spinning at a thousand miles an hour, and the entire planet is hurtling round the sun at 67,000 miles an hour, and I can feel it. We're falling through space, you and me, clinging to the skin of this tiny little world, and if we let go... That's who I am. Now forget me, Rose Tyler. // Doctor Who 1.01: Rose
