While I understand the necessities of spending one's time to ingratiate oneself to those who stand in authority over one, Mr Moon, it is extremely discourteous to disrupt another's schedule to do so. Had I known you would need to be elsewhere, I would have been able to remain in New London for the afternoon rather than returning to the castle early. In future, notify me as soon as you realise you must reschedule.

I must admit, however, that I am curious about the information you presented to Madam Umbridge. Do bring it with you.
