"Stories concerning selkies are generally romantic tragedies. Sometimes the human will not know that their lover is a selkie, and wakes to find them gone. In other stories the human will hide the selkie's skin, thus preventing it from returning to its seal form. A selkie can only make contact with one human for a short amount of time before they must return to the sea. They are not able to make contact with that human again for seven years."
