Lily was renowned for her desire to achieve perfection in everything she undertook. Whether it was school projects, art assignments, or even helping her parents with household chores, Lily’s commitment to excellence was unwavering.
One sunny summer day, Lily’s family decided to spend a day at the beach. As they arrived, Lily’s eyes were immediately drawn by a group of children who playfully built and then tore down their sandcastles. They giggled and shouted, their excitement on full display. “How silly, ” she thought, not quite getting why they enjoyed doing that.
Lily, being herself, decided to build a perfect sandcastle that would become the envy of all beachgoers. She began to plan every detail in her mind, from the balanced structures of the towers to the delicate decorations. Then, she set about piling sand to make the towers and walls of her sandcastle. Painstakingly, she crafted each feature of her work, carefully smoothed the surfaces and adjusting every detail to her vision.
Jake, Lily’s younger brother, didn’t seem too concerned with building a fantastic sandcastle. He picked a spot nearby and amused himself with the sand. He scooped up handfuls of sand, let it slip through his fingers like grains of time, and then molded it into careless shapes with the carefree abandon of a child. Jake’s happiness was contagious. Mom and Dad joined him, laughing and joking over Jake’s playful creations. From time to time, they called out to Lily and invited her to join the fun, knowing that the pursuit of perfection could be exhausting.
Nevertheless, Lily stayed where she was, determined to create an impressive sandcastle. She frowned at Jake’s unconventional, abstract art-like sandcastle shapes and persisted in her efforts. However, the process didn’t go as smoothly as she had anticipated. The sand didn’t always hold its shape, and the waves constantly lapped at the edges of her creation.
Para 1: As the day wore on, Lily’s sandcastle kept losing its form.
