Boy & A Girl Thing

He's gross, she's got cooties
That's just how it's supposed to be
He hates dumb tea parties
She won't climb a tree
It's a boy and a girl thing
A girl and a boy thing
It's a boy and a girl thing
A girl and a boy thing
She'll stop wearin' pigtails
And get the braces off her teeth
He'll stop makin' faces
And start savin' her a seat
It's a boy and a girl thing
A girl and a boy thing
She'll start wearin' makeup
And he'll start noticin' the curves
They'll get a little nervous
When she's with him and he's with her
Is he gonna kiss me?
Wonder if she wants me to?
Awkwardly embarrassed
Not sure what to do
It's a boy and a girl thing
A girl and a boy thing
They'll throw around 'I love you's'
Start makin' plans to say I do
Start a brand new life together
And probably have some babies too
They'll fight and act like children
And make up like they're seventeen
And even when they're eighty
It's still gonna be
A boy and a girl thing
A girl and a boy thing
A girl and a boy thing
A boy and a girl thing
