Sue is a kind and intelligent 12-year-old girl and Collin's classmate and friend. A talented young pianist, she's empathetic and understanding, almost motherly in some ways, though has a habit of not voicing her own insecurities and hardships or trusting others with her deeper feelings. Her voice is calm and gentle at some times and childish and cheerful other times. As mature as she can be, she's still just a kid. It's important for her to sound more her age and not hammy or overdone or overly motherly, so don't consider breaths or little vocal mistakes to be unprofessional.
