He's gross, she's got cooties.
That's just how its supposed to be.
He hates dumb tea parties, and she won't climb a tree.
It's a boy and a girl thing.
A girl and a boy thing.
She'll stop wearing pig tails, get the braces off her teeth.
He'll stop making faces, start saving her a seat.
It's a boy and a girl thing.
A girl and a boy thing.
She'll start wearing makeup and he'll start noticing the curves .
He'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 embarassed, 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 making plans to say I do.
Start a brand new life together
And probably have some babies too.
They'll fight and act like children.
Make up like they're 17.
And even when they're 80, 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.
