We often think we need words to fill our world, here two brothers (presumably) are scattering the ashes of their father in a tranquil and beautiful setting. Nothing is said apart from one enquiring whether the bag containing the ashes is to be washed out with the sea water.
I like it. I always think there should be words noise and such, but this meant a lot to them, they had clearly gone to some trouble so each to their own I say.
