The thought alone brought a rush of euphoria to Clara’s heart. She imagined a playful ferret, scampering across the floor, bringing a vibrant, energetic atmosphere to their apartment. She knew, though, that Lily, her roommate, would be hesitant. Still, she felt that anything was possible.

She tapped her foot rapidly, a wide grin lighting up her face as she gathered art supplies.

The world seemed bright, full of possibilities.
