My sister named her Cockatile "Hedwig" upon the urging of her freinds. I have noticed my self a increase in the use of common british slang by the people around me, but whether it is from Harry Potter, Terry Pratchett, Monty Python, the ol' "british invasion", the people i hang around, something else or a combiation of any of these i do not know.My whole family has read all four books and agree they are great! Good storytelling.
