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 don't really want to stay but you don't really want to go. 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.
