We all have many emotions, and they're all an essential part of life. You can't fully appreciate joy without knowing sadness. Kids and parents should communicate honestly and openly to each other about how they're feeling, even when it's hard. Family and friendship help make us who we are.

Additional themes include compassion, perseverance, and teamwork.
