Draco sighed but allowed himself to be distracted from his displeasure, "Your   friend, you mean," Draco said shrewdly, and Harry realised for the first time that there was a letter tied to the small owl’s leg, "I tried to take it off for you, but this little guy wouldn’t let me. I think someone has given him very strict instructions on who this letter is for, and not to let anyone else touch it," Harry leant forwards curiously, and gingerly unwound the twine that had bound the letter to the owl’s leg. Now unburdened by its delivery, the owl edged closer to Draco for a moment, releasing a soft hoot of enjoyment at Draco’s scratching fingers, before it took off from the table with a rapid beating of its wings.
