"So unimpressed but so in awe Such a saint but such a whore So self aware so full of shit So indecisive so adamant I'm contemplating thinking about thinking It's so frustrating just get another drink in Watch me come undone
So rock and roll so corporate suit So damn ugly, so damn cute So well trained, so animal So need your love, so fuck you all I'm not scared of dying I just don't want to If I stopped lying I'd just disappoint you I come undone"
