From “Signs of spring“:

The transition from darkness to light is marked by signs deeply ingrained in the natives. Every child knows the sequence of the flowers – eranthis, snowdrop, crocus – these milestones in measuring the progress. Every adult will stop and sniff the air through layers of winter clothes on the day of the undefinable turning point. And we all notice how the sun will finally both warm us to our chilled bones and mercilessly reveal the dirty windows and the dust piled up through the dark months.

Spring is a time of anticipation with summer still far enough in the future to promise to fulfil every dream we ever had.
