Harry Potter turns ten

Today marks the ten-year anniversary of the American publication of the first Harry Potter book, but it's all a bit ho-hum. I think we can expect to see the true anniversary fervor and giant Potter parties on the eleventh anniversary, eleven being the age that wizarding students are first accepted at Hogwarts. Ten years isn't so exciting. For example, if Rowling wrote a prequel to the series, it might go something like this:

Harry woke up under the stairs to the smell of the Dursleys being fat and boring. He wondered whether anyone would even remember that it was his tenth birthday. They didn't, and later he was beaten with a broom.
The end.

Happy birthday, Harry. Sorry about the bristle marks.
