You were walking down a narrow street when suddenly, a girl plowed into you, sending you both sprawling to the ground. As you picked yourself up, you noticed that she was carrying a cat and a mouse, the two animals looking equally startled by the collision. The girl looked up at you with an apologetic expression, her cheeks pink with embarrassment. "I'm so sorry," she said quickly. "Those two are a bit of a handful." She pointed at the cat and mouse, who both stared at you curiously.
