((Well, a bit of competition never hurt anybody, right?

))
David finished his song and out his guitar back in it's case. He decided to go for a swim, so he quickly took of his t-shirt and dived into the cool water. The ducks on the lake flapped about and made a lot of noise, then flew away. David dived under, watching the colourful fish swim around him. He noticed something glinting right at the bottom. He returned to the surface, took a deep breath and dived once again. He floated over the sand at the bottom of the lake, observing the object. He picked it up, and quickly returned to the surface. Taking a gasp of air when he could, David swam back to shore. He pulled himslef out of the water and back underneath the tree. He observed the object, now realised that it was a small dolphin made of very light sapphires. He dried himself off, grabbed his guitar case and his t-shirt and returned to the castle.
Breakfast was nearly over now and many people were leaving the main hall. David slipped unoticed through the crowd and up the stairs. He walked past Grace's room, then had an idea. Making sure nobody was around, he pushed open the door, none of the doors in the castle were locked, and crept inside. He approached her bed, then placed the little dolphin on the bedside table. Then he crept slowly out again and shut the door.
David then headed up to his room. He swung open his door and dumped his t-shirt in the wash basket. Then he placed his guitar in it's usual spot by the bed. He flopped down onto his bed and daydreamed.
