With chapter titles, I have often spent 15 minutes just thinking of one, only to change it half-way through the chapter.
I also try and think of obscure phrases to use: "Strangers in the Night" for example, which is a quote from the old computer game Blood, in turn stolen from some unknown tune. Something that fits the content of the chapter, and yet has other meanings
As for titles, "Julie" isn't exactly the most descriptive, but I have no idea what else I could call it! (And no, I'm not changing it )
