Lydia and Gideon were jumping and diving their way through Costco. They leaped and bound from one island to the next as they were only allowed to step on shadows made by the massive pillars of cereal and protein powder. Then they suddenly came to an ocean where no shadows were in reach. They were stuck on the edge of the world. Their family moved ahead without them, hardly noticing the two castaways left behind on the shadowy shoreline.
Suddenly Gideon had an idea. They could walk on their own shadow! You see, he explained, there is always a shadow underneath their feet. In this way, they could actually walk where ever they felt like without danger of being swallowed up by the floor.
Hand in hand the two of them confidently stepped off of their island and danced away on the surface of the water. And it was a bit like growing up.
