"Old Lady" lyrics

When I'm an old lady
I'm gonna be his baby
I'm gonna wrap myself around him
And then I'm gonna kiss him

But that's a way down the line
You see for now he isn't mine
But I don't mind waiting
And the longing's not aching

Cause I know
One day he'll say, "that's my girl"
The happiest words in the world
Make me laugh like an idiot
Not be so serious

For now when I'm around him
I act like I don't care for him
I even act like I don't like him
Ignore him, to spite him

But only so that I won't smile at him
For everyone would know I love him
And that's so uncool
Cuz it's messing with all the rules

And I know
One day he'll say, "that's my girl"
The happiest words in the world
Make me laugh like an idiot
Not be so serious
