I once joined a Harry Potter contest myself — it was a diorama contest for the launch of Harry Potter and the Half-Blood Prince, and my entry — a papier mache diorama (that took me two weeks to make!) of the first task in the Triwizard Tournament — Harry and the Hungarian Horntail.
I was not supposed to join the contest, but Dianne talked me into it because she planned to submit an entry too. So in a panicky fit, I started making mine, and just when I was halfway through, Dianne tells me she can’t go through with her entry and I was too far in to quit!
