Caillou asks Daddy for his ball, but Daddy is busy. While Caillou waits, he plays with a stuffed animal. But the stuffed toy doesn t listen to him, so Caillou speaks very loudly. Daddy advises Caillou to be more gentle with his toy. Caillou learns that asking politely can result in a more positive response.
Politeness is a social convention. It is also a way to smooth human interactions. Even the smallest children can learn to express their needs politely.
