Here's my final idea for her character: Perrin is a quiet girl who likes to dance, garden, and write. She's not especially competitive and likes to keep to herself, but also enjoys spending time with her friends. Perrin loves to learn about outer space, and enjoys sushi and butter pecan ice cream.
Perrin, what are you doing with that physics book?
Well, I thought you were busy so I decided to get it from your shelf. It was awfully heavy - I had to get Violet to help me. Anyway, this stuff is really interesting.
It sure is, but it's not safe for you to be climbing around those heavy books. I'll make you your own physics book if you promise to leave mine alone, okay?
It's a deal if you get me an ice cream cone too.
