I should've known by the way you passed me by, there was something in your eyes and itwasn't right.I should've walked but I never had the chance, everything got out of hand and I let it slide.Now I only have myself to blame for falling for your stupid games.I wish my life could be the way it was before I saw your face.You stole my happy, you made me cry, took the lonely and took me for a ride and I wannaun-un-un-un-undo it.You had my heart, now I want it back, I'm starting to see everything you lack.Boy you blew it, you put me through it, I wanna un-un-un-un-undo it.Na-na-na-na-na, na-na-na-na-na, na-na-na-na-na-na.Now your photos don't have a picture frame and I never say your name and I never willand all your things, well I threw them in the trash and I'm not even sad.Now you only have yourself to blame for playing all those stupid games, you're always gonnabe the same.Oh no, you'll never change.You stole my happy, you made me cry, took the lonely and took me for a ride and I wannaun-un-un-un-undo it.You had my heart, now I want it back, I'm starting to see everything you lack.Boy you blew it, you put me through it, I wanna un-un-un-un-undo it.Na-na-na-na-na, na-na-na-na-na, na-na-na-na-na-na.You want my future, you can't have it, I'm still trying to erase you from my past,I need you gone so fast.You stole my happy, you made me cry, took the lonely and took me for a ride and I wannaun-un-un-un-undo it.You had my heart, now I want it back, I'm starting to see everything you lack.Boy you blew it, you put me through it, I wanna un-un-un-un-undo it.You stole my happy, you made me cry, took the lonely and took me for a ride.Boy you blew it, you put me through it, I wanna un-un-un-un-undo it.
