Notice that the stiffest tree is most easily cracked, while the bamboo or willow survives by bending with the wind.
— Bruce Lee

The willow is my favorite tree. I grew up near one. It's the most flexible tree in nature and nothing can break it - no wind, no elements, it can bend and withstand anything.
Pink willows quote

The willow which bends to the tempest, often escapes better than the oak which resists it; and so in great calamities, it sometimes happens that light and frivolous spirits recover their elasticity and presence of mind sooner than those of a loftier character.
— Walter Scott

These heroes are dead. They died for liberty - they died for us. They are at rest. They sleep in the land they made free, under the flag they rendered stainless, under the solemn pines, the sad hemlocks, the tearful willows, and the embracing vines. They sleep beneath the shadows of the clouds, careless alike of sunshine or of storm, each in the windowless Place of Rest. Earth may run red with other wars - they are at peace. In the midst of battle, in the roar of conflict, they found the serenity of death. I have one sentiment for soldiers living and dead: cheers for the living; tears for the dead.
— Robert G. Ingersoll

Glorious are the woods in their latest gold and crimson,Yet our full-leaved willows are in the freshest green.Such a kindly autumn, so mercifully dealingWith the growths of summer, I never yet have seen.
— willows quotation by William Cullen Bryant
