Growing Up

This is a bit of a drabble turned into a story from a little thing I thought of. What would happen when a trio of Order members are accidentally turned back into their youth? Eventual Harry/Snape bonding...with Remus, Sirius and Albus! No slash. Canon-compliant, but a bit AU obviously.XD Set in summer before fifth year. More light-hearted but with tense/dark moments.
