[Rachel]   You change your mind   Like a girl changes clothes   Yeah you, PMS   Like a bitch   I would know      And you over think   Always speak   Critically      I should know   That you're no good for me      {CHORUS} [Girls]   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   (but you) But you don't really want to go-o   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      [Rachel]   We used to be   Just like twins   So in sync   The same energy   Now's a dead battery   Used to laugh bout nothing   Now your plain boring      I should know that   you're not gonna change      {CHORUS} [Girls]      [Rachel]   Someone call the doctor   Got a case of a love bi-polar   Stuck on a roller coaster   Can't get off this ride         [Girls]   You change your mind   Like a girl changes clothes
