I used to live in a darkened room   Had a face of stone and a heart of gloom   Lost my hope, I was so far gone   Cryin' all my tears with the curtains drawn      I didn't know until my soul broke free   I've got these angels watching over me, yeah      Oh watch me go, I'm a happy girl   Everybody knows   That the sweetest thing that you'll ever see   In the whole wide world is a happy girl      I used to hide in a party crowd   Bottled up inside, feeling so left out   Standing in a corner wearing concrete shoes   With my frozen smile and my lighted fuse      Now every time I start to feel like that   I roll out my heart, I like a welcome mat      Oh, watch me go, I'm a happy girl   Everybody knows   That the sweetest thing that you'll ever see   In the whole wide world is a happy girl      Laugh when I feel like it, cry when I feel like it   That's just how my life is that's how it goes      Oh, watch me go, I'm a happy girl   And I've come to know   That the world won't change just 'cause I complain   Let the axis twirl, I'm a happy girl      Oh watch me go, I'm a happy girl   Everybody knows   That the sweetest thing that you'll ever see   In the whole wide world is a happy girl      Oh yeah, oh yeah   I'm a happy girl
