A delightful simile for a late-landing spring, that of a boy running to school. It also reminds me of another description of a delayed spring bounding in.
It was the end of April, and the belated spring was flushed and warm, like a youngster who has run all the way to school lest he be punished. The meadows, forests and clouds race to unleash their colors in the sage-scented sunshine.
