Reach for this book when your child is starting to experiment with social boundaries or needs to understand that their actions have ripple effects on others.

Through the relatable lens of a substitute teacher day, it explores the messy reality of trying to be someone you're not. The story follows two best friends who swap identities when a substitute teacher arrives, only to find that living another person's life (and academic reputation) is far more stressful than they anticipated. It tackles themes of honesty, social pressure, and the value of one's own identity. For parents, it serves as a gentle, humorous springboard for discussing integrity and the importance of being accountable for one's choices without being overly preachy.
