I'll tell you why it won't work baby You're coming off as pretty lazy I put in too much You don't do enough I'm leaving you with feelings of hating I'm sick and tired of simply waiting You needed to show me I was more than a showpiece You keep wronging me Quit saying you're loving me All you want's to have fun with me But that's no fun for me That's why I'm singing... Na na na na na na (Na na) Na na na na na na (Na na) Na na na na na na (Na na) Na na na na And that is why I'm leavin' baby! Second time I know I'm a fool I'll say I'm fine and I'll play it cool I needed an out I was so blind, wow Take it from a girl who's still lovin' You used me up, pushed me, and shoved me Yet you are so empty I've been full since you left me You said it's not you, it's me You're damn right it isn't me All you want's to have fun with me But that's no fun for me That's why I'm singing... Na na na na na na (Na na) Na na na na na na (Na na) Na na na na na na (Na na) Na na na na And that is why I'm leavin' baby! You said it's not you, it's me You're damn right it isn't me All you want's to have fun with me But that's no fun for me That's why I'm singing Na na na na na na (Na na) Na na na na na na Na na na na na na na na (Na na) (I'm leavin') Na na Na na na na na na (Na na) Na na na na na na (Na na) Na na na na na na (Na na) Na na na na na na And that is why I'm leavin' baby!
