We were on the beach, in the sea, playing with Gwyn, although we learned two things, first he was afraid to go in the water, and second he didn't know how to swim. But little by little we got him to go in, at least as far as he could tread, and we tried to get him to learn to swim.
Vel wondered how, at her age, Gwyn didn't know how to swim, apparently that is something that is taught early on in the long-lived, but in humans, it was very deferential to the parents, and well, it's clear that no one had taught her.
We made her kick a little at a time in the water while we guided her, she was a little scared, but she was doing well. Besides, the most tender part of all this, was the effort Vel was trying to make for her to learn.
