I don't usually talk about personal stuff here, but I'll make an exception:
I got tired of telling our two year old daughter the same old stories about children lost in forests, bears, witches, evil stepmothers and so on, so I turned to some other material I know fairly well. I started recounting simplified bits and pieces of the first Star Wars movie over the course of a week. She thought it was great fun, what with wookies and robots and a princess and lots of adventures, and now, every evening, asks for "Skywalker story!". I'm quite proud, although my wife rolls her eyes a bit.
