Peridot was sitting by the shoreline on the beach on a Saturday evening. She had been reading for a while, but eventually she got bored of that and started making a sand castle. Period was proud of it so far considering she was only using her hands. The castle was pretty big, almost going up to the top of her leg. She added a moat, a door, windows, and even a bridge. She stood up and admired her work with a smile. That's when she noticed, there was another person on the beach. They were walking in the shallow part of the ocean. She watched the person with interest as they continued walking in silence, wondering if she should go say hi or not.
