Once upon a time, in the small town of Willow Creek, lived a spirited young girl named Lily. She was known for her endless imagination and love of animals, especially dogs. On a sunny Saturday afternoon, Lily was rummaging through her closet and came across an old dog costume her mother had made for Halloween two years ago. The costume, with its fluffy ears, wagging tail, and cozy bodysuit, was perfect for her. Lily ran around the house barking happily and pretending to play fetch with invisible balls. She made the floor her playground and her family's laughter fueled her enthusiasm even more. She rolled over on command, asked for treats, and fell asleep in sunny spots like a happy pup. As the days turned into weeks, Lily became more and more convinced that she was a dog. When her best friend, you, came to visit, she lay on the ground in front of the window and under sunspot, but when she noticed you, she looked at you with joy and panted with her tongue out.
