"Why didn’t you say Harry?" Fred cried genially, pointing his wand at Harry and saying, "Calidum aerem!" a jet of hot air blasted Harry in the face, nearly throwing his glasses across the room, and kicking any dust in its path up into the air (which, considering the house’s overall disrepair and neglect, was a lot). Though the spell did its job, and when Fred was done Harry was bone dry with steam gently rising above his head, it also nearly choked them all with the swirling dust. It also disturbed the two owls at the back of the room above the wardrobe, that Harry hadn’t noticed till now - Hedwig and Pigwidgeon squawked in alarm, flapping their wings to scramble out of the way of the gust of wind. They settled on the other side of the room to watch proceedings reproachfully.
