Conjuring some entertainment under the stairs

Uncle Vernon, steaming with rage at Harry’s latest inadvertently magical misdeed, throws the poor young orphan into his room under the stairs and slams the angled door shut. “You aren’t coming out of there for a week, boy! Do you hear me?! A week!”

Dust sifts down from the underside of the staircase onto the back of Harry’s head, and he brushes it off while he gets back onto his feet. Harry smiles, knowing that no matter how long he stays in the cupboard under the stairs, he’ll manage to feed and entertain himself with the magical skills he had learned at school. He flicks his wand at the slanted roof and casts “Lumos”, filling the small room with soft golden light.
