grandma tends her field year after year. Each harvest, she accumulates towering stacks of grain behind her cottage. Layer upon layer, the piles grow so high they block the sun. Grandma never stops—every season the field yields more, and she heaps it all on top of what came before.
Additional thoughts
Picture an old grandmother in a rice field, endlessly stacking sheaves into an impossibly tall tower. The image of repetitive layering in a field ties directly to accumulation over time.
