There was not a single cloud in the sky. Against the sharp and strong silhouettes of buildings the sky was a deep, rich, almost overwhelming blue, from as far as it meets with the ground to the very top of anything you can see. Days like these, when the sun is on my back and I can see as clearly as I could, humble me – how little, how nothing I am next to the roof of this Earth. How many miles am I actually looking at when I open my eyes wide and stare at the blue openness. What stars look back at me, invisible until the sun sets, made out of the same things yet impossibly different from me. I am conscious of it – though I really have no understanding.
