"I don't remember my reaction [when she found out that the Puerto Rican writer she thought was her father wasn't her father at all: she had been brought up thinking herself to be half Puerto Rican and suddenly she wasn't - ed.] because I wasn't very demonstrative as a kid, but it was probably some sort of embarrassment, and wondering what the hell this was about. Like, Oh, that's interesting. Let me go away and think about it for ten years. Suddenly I felt that everthing I had known was kind of stripped away, which is a feeling I've had often and I think that's probably had a lot of effect on my songwriting. Because every time I look at someone I think, you could strip everything away. You could strip away their name, you could strip away their beliefs, strip away who they think they are and you'd still have a person there you have to address. So when I write, that's the part of the person I'm aiming for - the part that's been stripped away. […] I did [write a song about the particular situation of finding out your father isn't your real father - ed.], but not in the way you might think. There's a song I wrote on the Philip Glass album, 'Songs From Liquid Days' [Freezing - ed.] I don't think even Philip Glass knows what the song was referring to. Because I remember my father once asking me those questions exactly and, of course, later on I found out why. […] I guess it clarified a few things. I had suspected I was different in some way, although I didn't know what it was and maybe that put the finger on it."
