I `I don't want to...' And `I can do it by myself'

Brother and sister Millie and George, have very different ideas from their parents. George likes to do things by himself, yet he soon finds out that sometimes a little bit of help goes a long way. Millie, on the other hand, doesn't want to do a lot of things. She is far too grown up to be told what to do. Yet, when Teddy, her best friend gets to do everything, Millie soon changes her mind.
