I should know that you're not gonna change .

You change your mind like a girl changes clothes ; yeah you PMS like a b i t c h I would know . And you always think , always speak correctively . 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 and you're out , you're up and 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 . You're hot then you're cold , you're yes then you're no , you're in and you're out , you're up and you're down . 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 .. 'cause you're hot then you're cold , you're yes then you're no , you're in and you're out , you're up and 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 . You're hot then you're cold , you're yes then you're no , you're in and you're out , you're up and you're down . Someone call the doctor , got a case of a love bi-polar .. Stuck on a roller coaster , can't get off this ride . You change your mind like a girl changes clothes .
