"Female selkies are said to make excellent wives, but because their true home is the sea, they will often be seen gazing longingly at the ocean. If she finds her skin she will immediately return to her true home, and sometimes to her selkie husband, in the sea.
Sometimes, a selkie maiden is taken as a wife by a human man and she has several children by him. In these stories, it is one of her children who discovers her sealskin (often unwitting of its significance) and she soon returns to the sea. The selkie woman usually avoids seeing her human husband again but is sometimes shown visiting her children and playing with them in the waves."  Wikipedia

Playing "The Silkie" on the harp.  Missed the significance until I heard 3 young women walking on Hawthorne talking as they passed.  I realized why I couldn't find the feeling of the song, written by Christina Tourin.  Now looking for my skin.
