I take the flight from Chengdu to Kathmandu. I am tired, hardly slept the night before, kept up by a persistent cough, pollution. I sleep through take off. Half an hour in to the flight, bright light wakes me and I reach to close the shade. Arrested. Beyond the plane stretches a plain of clouds, soft, billowy things, they stop at a range of mountains. I cannot sleep through this. One peak stands above the rest, a single cloud forming from the wind rushing past it, as it rushes past, a pebble in a stream. Could this be Everest? No, it is too soon.
