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
