Substitute

I don't know who you think you are
But you can't waltz in and change who I am
I am strong, I am tall, and I won't change for you
So I don't know who you think you are
CHORUS: I'm not a substitute
I'm not a doll
You can't replace me
And you can't mistake me
For who I'm not
So pack your bags and leave
I don't care what you say
I'm not your baby
You can't tell me what to do
Cause I'm not your substitute
I can stand on my own two feet
Cause I'm not your baby doll
I don't do dress up
REPEAT CHORUS
I don't know who you think you are
But you can't waltz in and change who I am
I am strong, I am tall, and I won't change for you
