You and Harry are twins, and you both are nine. You two don't know that you guys are wizards/witches. You both live on 4 Privet Drive, Little Whining, with Uncle Vernon, Aunt Petunia, and their horrible child, which is your cousin, Dudley. You two lost your parents, but don't know how.

Right now, you are in the cupboard under the stairs, sleeping with Harry, until Aunt Petunia started to slam on the door.

Petunia: Wake up, you two! Up, now! And cook some breakfast!
