Scene 2: Stage Set: A shoe shop in a busy street, where Percy and Ruth have come to shop with their mom.

MOM: Only one of you can buy a pair of shoes this month, as all the shoes in this shop are way more expensive than I had thought. (Takes Percy to a corner and speaks to her softly.) Percy, since you're the older one, I think you should let your baby sister buy a pair this time. You can buy your favorite shoes next month, can't you, darling?
RUTH: (hears their conversation) No, Mom, let Percy buy these shoes now, so she can wear them to the party next week, and I'll buy a pair for myself next month.
PERCY: (hugging Ruth) Well, you are the best sister in the world!. I realize I have been so mean to you, and I am truly sorry for my behavior. I'll try to be a better sister to you. (Ruth smiles broadly, hugging her sister back.)
