" You change your mind Like a girl changes clothes Yeah you PMS Like a bitch, I would know And you overthink Always speak cryptically I should know That you're no good for me 'Cause you're hot then you're cold You're yes then you're no You're in then you're out You're up then you're down You're wrong when it's right It's black and it's white We fight, we break up We kiss, we make up You! You don't really want to stay, no You! But you don't really want to go-o We used to be Just like twins, so in sync The same energy Now's a dead battery Used to laugh 'bout nothing Now you're plain boring I should know that you're not gonna change Someone call the doctor Got a case of a love bi-polar Stuck on a roller coaster Can't get off this ride "
