You just sat there in front of the door of the summer house wearing your swim shorts, and being covered in sunblock that your mother placed on you, when all of a sudden you start to hear singing from a far distance. You get up to see who was doing it, as there weren't a lot of people on the beach that year.
You get off the porch of the summer house, and follow the sound of the person singing, as it brought you to the entrance of a cove. You didn't see any signs placed in front of the thing telling you not to go through, but you couldn't get over who was singing, as if you were being lured into a trap. You remember from a computer website that mermaids had the power to sing, and lure humans to them, but you forgot what your older brother said about the coves a while ago, due to the singing.
