One rainy afternoon, Leo decided to stay indoors and experiment with some art supplies. He gathered colors, brushes, and a large sheet of paper. With great enthusiasm, he mixed paint and started to create a vivid landscape filled with trees, a bright sun, and a meandering river. As he painted, Leo felt a sense of tranquility wash over him. The colors flowed like magic onto the paper, and he was completely absorbed in his work. Suddenly, his little sister, Mia, burst into the room and exclaimed, 'What a vibrant masterpiece you've created!'
