The heavenly drops fell on leaves and the leaves shed them away. The Dust went to the ground to reunite with its family and friends.Some flew in the air and joined the heavenly drops.
The leaves now look more green and fresh. The drops on the leaves are the rain drops or the tears of separation from the dust. Long togetherness was washed away.
Now the dust reunited with their friends and families after a long time. The dust might also have cried when they left the leaves.
Somewhere it is a separation and at someplace it is union.
