I was over at Alison's [McGhee], I think we were playing Scrabble. I remember we were both complaining - yeah, we sound like whiners - about how hard writing is, and how we didn't have a story to work on. Alison said, 'Why don't we work on writing something together,' and I said, 'Eh, I don't know if I could work that way.' She said, 'Well, just show up here and we'll see,' and I said, 'Well, what would it be about?' She said, 'Duh, it'd be about a tall girl and a short girl.' So I agreed to come and try it for a day.
