Overlooked by the light of day, weeds and wild flowers of all kinds luxuriated quietly, glad of the interval for dreams beyond the margin of time on the borders of an endless day. An enormous sunflower, lifted on a powerful stem and suffering from hypertrophy, clad in the yellow mourning of the last sorrowful days of its life, bent under the weight of its monstrous girth. But the naive, suburban bluebells and unpretentious dimity flowers stood helpless in their starched pink and white shifts, indifferent to the sunflower's tragedy.”\00000a \00000a One must imagine the sunflower happy."; }
