Whispers in the Cave

 This is a small idea I have for a story, free to a good home...  Two old married people live in a set of caves on a mountain for decades.. She tended the gardens, he tended the ponds for fish. They could not hear each other all day so they whispered I love you in a box so they could hear the other whenever they pleased. Then, as time moved on just before they died as one, they released the boxes into the caves. The whispers became the echoes in the cave, telling I love you to everyone that entered, a reminder of their love.
