A man sat by the shore at the beach.
Two little boats, sailing along the coast..., he muttered.
That sounds like the beginning of a story, someone in the group said, laughing. And continued walking.
Two little boats, sailing along the little coast, sailing along the rocky coast, sailing along... And he stopped, his eyes on the horizon.
The group had disappeared from his sight.
Two little boats, sailing along the sharky coast... He stopped again. Sharky... Shark. He shook his head and slid backwards, taking his feet out of the water.
One little boat, sailing along the lonely coast.
