You can thank someone for understanding in a bunch of ways. Write a note. Hug it out. Verbally share your gratitude. Or you can give a hydrangea, a wildflower that grows in sizable heads on bushes sometimes exceeding 6 feet tall.
Hydrangeas come in blush tones: white, pink, bluish purple and bright blue. The level of acid in the soil can dramatically affect the flower's color. In general, low-acid environments yield bluer flowers, and higher counts produce pinker flowers. Some see the hydrangea as a powerful metaphor for life: We can change what we manifest in our outer world by first changing the soil of our inner world, like thoughts and beliefs.
