You Never Know What You'll Find In a Sand Castle

Two little five year olds bump into each other at the beach one day. With a bit of digging in the sand they make their first sand castle, which is soon washed away by the tide.

Left over is nothing but a broken shell split in half. And a friendship remembered for a lifetime. (This is just a little short story I had an idea for. Tell me if you want a chapter or two more or if you would rather it just stay a little story :). Thanks!)
