One couple after another moves through the gardens with the same aimlessness. They pass the flowerbed and are enveloped in the green-blue vapors that give their bodies substance and a dash of color. But this soon dissolves into the atmosphere. This afternoon, it is so hot that even a thrush seeks the shade of the flowers. Butterflies dance above the flowers. The glass roof of the palm house shines as if it were a whole market full of shimmering green umbrellas that were opened in the sun.
