Tim is in trouble with his mum because he won't share with his little brother Jack. He goes next door to visit the twins. Kay and Kathy grew up sharing things. He plays with them all afternoon and begins to see that sharing makes things more fun. A football or a pet, for example, is so much more enjoyable if you share it with others. Tim lets Jack share his walkman. Later, Jack offers him a piece of his cake. Tim sees that once you learn to share with others, they may well learn to share with you!
