I watch the circular waves expand across the pool's surface. When they reach the bank, they splash up, leaving a mark, evidence of their existence even after they have gone.
Splash! A smile at a stranger. Ripple: she smiles back, then later holds the door open for a woman burdened with a squirming child and overflowing shopping bags. She is grateful for the kindness.
Splash! A box ticked on a consent form. Ripple: your choice means others get another chance at life; families are given a reprieve from grief.
I imagine their gratefulness and smile through my tears.
