Foreshadow: to represent, indicate, or typify beforehand.
Precursor: one that precedes the approach of another.
These leaves shout something, but what? Are they crying, “Fall is coming,” a herald in this lush land, warning the chlorophyll of its imminent demise? Unashamed of showing their true colors over the need to get out the message, they proudly precede the wonder of blazing hills. And so they go mostly unnoticed: no pointing with oohs and ahs, no photo ops with the kids, no cover photo on Facebook. Self-effacing, a precursor to all the rest.
But foreshadowing connotes a darker theme on the other side of beauty: falling and barrenness, a cessation of rustling. Canopies and shade give way to the realities of disease and the evidence of forgotten wind and ice and careless pruning. A silent world with all its skeletons on display.
