I think this song talks about the way he behaves and how it can sometimes be compared with the way he used to act when he was a little kid and how he hasnt changed in some aspects but also with the way a more mature person tends to be. It's a way to show us how we may still have a chilidish behavior sometimes but we're still maturing.
