I don't see... it might've been kicked... oh! There it is." The edge of the tray was peeking out from under the sofa's dust ruffle. Using his own wand, he cast the spell, "Accio tray," and it came flying to his outstretched hand.
"You ought to be a bit more careful. It would've been a loss if those cookies were wasted." As he spoke, he used another Charm to clean and dry the tray's surface before the cookies were placed upon it again. "What kind are they?" he asked... they looked rather yummy.
