I'm just a girl   You're just a boy   This is my heart   It's not a toy   So what's with you playing with my mind?      We used to be cool   This used to be love   Now it's become   Something like a job   Like it or not   Maybe things were changing   Right before our eyes      - pre-chorus:   I tried to be your picture perfect girl   But you were in your own fantasy world   Trynna control me   Like some kind of barbie   But that just ain't me      -chorus:   'Cuz I ain't a doll   This ain't a dollhouse   You're way too old to be   Putting me down like this   And playing around like this   I ain't a doll   This ain't a dollhouse   No i could never be stuck living life like this   Behind these four walls   I ain't a doll      You call the shots   Right down to my shoes   I liked what you liked   Cuz you told me to   And i don't think that you could even tell   I fell out of love   But it never showed   I gave up on us   So long ago   But you'll never know   Baby don't pretend like you know me so well      -prechorus:      I tried to be your picture perfect girl   But you were in your own fantasy world   Trynna control me   Like some kind of barbie   But that just ain't me      -chorus:      I ain't a doll   This ain't a dollhouse   You're way too old to be   Putting me down like this   And playing around like this   I ain't a doll   This ain't a dollhouse   No i could never be stuck living life like this   Behind these four walls   I ain't a doll      I'll never be made of plastic   So glad that my heart's elastic   No matter what you do   I'll bounce back off of you   Cut me but i'm not bleeding      -prechorus:      I tried to be your picture perfect girl   But you were in your own fantasy world   Trynna control me   Like some kind of barbie   But that just ain't me      -chorus:      I ain't a doll   This ain't a dollhouse   You're way too old to be   Putting me down like this   And playing around like this   I ain't a doll   This ain't a dollhouse   No i could never be stuck living life like this   Behind these four walls   I ain't a doll      And i come with imperfection   Epitome of perfection   If you can't understand   Loving the way i am   Then you're no good for me   So glad i kept my receipt
