Worry Warriors: Edgy Estella Aces the Sleepover Party

Estella has just been invited to her first sleepover party. She wants to go, but she's nervous about sleeping in someone else's house. Plus, the theme of the party is art, and though she's a great dancer, she's not so good at art. Or math. If she can't master her multiplication tables, her parents won't let her go to the party at all. Now she's worried: what if she can't go to the party? Or worse, what if she does and is miserable the whole time?
