Mia and Carla became friends on their first day of elementary school. Mia was quiet and enjoyed drawing, while Carla was energetic and loved talking to everyone. They seemed completely different, but they quickly became inseparable. They shared lunches, secrets, dreams, and school projects. Whenever Mia was afraid to speak in class, Carla encouraged her. Whenever Carla forgot an assignment, Mia helped her finish it. "We will always be best friends," Carla said one afternoon. "Even when we are old," Mia answered. Years passed, and their friendship remained strong. They entered high school together and joined the school journalism club. Mia became an illustrator, while Carla wrote articles.
