A fairy tale house sits on a small island in the middle of the sea. My daughters think that a part-time mermaid may live here (she's a mermaid part of the time, and human the rest of the time). I don't know, because I've never seen anyone come or go from the house. The little fish is quite curious about the interior of the house, but knows that a lengthy encounter with the fireplace inside could give him itchy, dry skin, so he has settled for jumping up to peer into the windows.
There is a teeny tiny little light (time for the Redundancy Police to spring into action) above the front door, inviting the owner and visitors to enter.
