I know with my kids, we spent three years for each of them reading the stories at bedtime, and it was probably one of the nicest memories I have with them. I go to theme parks… I probably go to three or four theme parks every year. I’m a huge theme park fan, and I don’t do it professionally; I do it because I’m a big nerd. When you go to the Harry Potter world inside of Universal Studios, A, they’re some of the best theme parks ever imagined, and B, it’s all ages.
