You might decide to build a boat. You might call it, "The Goat." You might cover yourself in charcoal. You might spend a quiet afternoon figuring out how to make pop up cards. You might nick a few hens eggs and dissolve the shells in vinegar. You might look up the recipe for fake flesh in preparation for Halloween. You might spend a long misty afternoon in the woods and parks around town, with an old friend, finding new letterboxes. You might tame another kitten. You might add a few skeleton keys to your collection. You might go to the library, come home, and read a fat novel all in one day. You might begin to notice for yourself that life is unpredictable. You might be home when all four hens finally begin to lay. You might have time to read and read and read and read and read just as much as you like. You might take up needle felting. You might even, occasionally, stumble into some hard lessons.
But no matter what you do, your parents will likely be astonished by your creativity, drive, freedom, sweetheartedness, and the joy you bring to their lives by just being yourselves.
