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 [bad word] 

 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
