Ep 5. Considerate Caillou

Caillou wants to learn to play a song on his little keyboard...only Rosie won't leave him alone. She keeps distracting him, trying to chime in with her drum, and pots and pans, and silly singing. When Caillou sees his sister playing on a 'pretend' keyboard - just like Caillou - he decides to let Rosie join in his music fun.
