To wrap up our series on responder values, a short story:
A young couple decide to go for a walk along a quiet sandy beach, just before sunset. Hand in hand they stroll along the edge of the warm surf. The waves leave soft white lumps of foam before they recess back to the sea. Ahead of the couple on the beach, an old man is also walking. He is moving slowly, almost gingerly along the water’s edge. Every few steps, he stops, slowly bends over and picks something up, then walks into the surf about knee deep, places that something into the water and then goes back to his slow stroll along the beach.
He does this over and over. The young couple, curious, walk closer behind the old man to see what he is doing, so intently.
