Sam, Frodo, gen fic about fishing and swimming.

A young Sam (12 to 18 years) takes Frodo to his favorite fishing spot and at some point during their fishing trip, Frodo offers to teach Sam to swim. Your choice as to how the topic comes up in conversation. What is Sam's reaction? Is he interested? Frightened? Shocked by the offer? Does he agree to it or argue against it? Why does Frodo offer in the first place?
