Snow

'Marcovaldo learned to pile the snow into a compact little wall. If he went on making walls like that, he could build some streets for himself alone; only he would know where those streets led, and everybody else would be lost there. He could remake the city, pile up mountains high as houses, which no one would be able to tell from real houses. But perhaps by now all the houses had turned to snow, inside and out; a whole city of snow with monuments and spires and trees, a city that could be unmade by shovel and remade in a different way.'
from Marcovaldo by Italo Calvino
