Through the icy window beside my desk I can see the playing fields. They are white with summer frost. The trees are lumps of blue and white, with large drifts leaning against them. Snow falls slowly and silently and steadily from a leaden sky.

Ever since the bomb tests, the Earth has been moving farther and farther from the sun. Some people are saying that, in a few years, our planet will be a frozen lump of rock, like Pluto.

I don't care what anyone thinks. I'm going to finish my drawing of the stairs.
