One sunny morning, Rose was playing by the beach. She loved to search for seashells and build sandcastles. As she dug her hands into the sand, she found something shiny. It was a piece of polished blue glass, sparkling in the sunlight. Rose wondered where it came from.

Rose decided to find out more about the mysterious blue glass. She asked her grandmother, who told her stories of mermaids who lived in the sea. Her grandmother said that mermaids sometimes left treasures on the shore. Rose's eyes sparkled with excitement as she imagined meeting a real mermaid. She knew she had to discover the truth about the glass.

The next day, Rose returned to the beach with her blue glass. She sat by the shore, hoping to see a mermaid. Suddenly, a gentle wave brought a beautiful mermaid to the surface. The mermaid smiled and explained that the blue glass was a gift from the sea. Rose listened in awe as the mermaid shared tales of the ocean's wonders.

Rose and the mermaid became friends, meeting by the beach whenever the sea was calm. The mermaid taught Rose about the ocean and its creatures. Rose promised to take care of the beach and keep it clean. She learned that treasures are not just things you find, but also the friendships you make. And so, Rose's heart was filled with joy and wonder.
