When I wanted to go back to the UK, Mum protested at first, but I knew how to get "round her. I explained that everybody who was taking the exams seriously would be back at Hogwarts studying, and these exams were terribly important, and she swallowed the whole story, nodding stupidly while she thought about the next party she was planning. Truth to tell, I think she was rather glad to be rid of me; she'd taken up with another rich "admirer," and having me around, observing everything but saying nothing, makes her nervous. As it should, since the second I need her to do something she doesn't fancy doing it'll be blackmail time.
