" - Katy Perry " My parents were strict, but it was the world I lived in. I had no idea there was a world outside. " - Katy Perry " I think sometimes when children grow up, their parents grow up. Mine grew up with me. We coexist. I don’t try to change them anymore, and I don’t think they try to change me. " - Katy Perry " The first songs I wrote were catchy, but the subject matter was God.
