(Sheppard and Kenny Gioia)

What do you want to be when I grow up
A teacher a nurse or a bum
I don't need you to judge what I did

Stop treating me like a kid
If I wanna change my mind with out asking you
If I wanna take my time than I'm going to

'Cause I'm a big girl
I'm a very good girl
Yes I'm a big girl
And you don't have to worry 'bout me this time
Just trust me I'll be fine

And hey yeah
Do you ever think of letting go
And hey yeah
Before I lose my mind

Everything I want to do you say no
When I ask you why, 'cause I told you so
If I wanna tie my shoes without help from you
Guess no one ever sheltered you

And hey yeah
What ya gonna do when I'm not around
And hey yeah
You can't me the clock unwind
I keep telling you

I'm a big girl
I'm a very good girl
Yeah I'm a big girl
And you don't have to worry 'bout me this time

Just trust me I'll be fine
And hey yeah
Do you ever think of letting go
And hey yeah
Before I lose my mind

I'm a big girl
And I'm not your little girl
Yeah I'm a big girl
And you don't have to worry about me this time
'Cause I'll be fine

I'm a big girl
I'm a very good girl
Yeah I'm a big girl
And you don't have to worry 'bout me this time

Just trust me I'll be fine
And hey yeah
Do you ever think of letting go
And hey yeah
