When am I going to grow up?!

I feel like a little girl
Trying to conquer the whole wide world
Everybody wants a piece of me
And I just don't know where to turn
I've got work piled up to my head
All I want to do is jump into bed
And wash away my troubles

All I need is a good disguise
One where nobody can recognise
That I'm feeling so small
All I need is a secret weapon
I've gotta have faith
Zapping monsters into outer space
I'm gonna be a Superhero

I missed my dad so much. He just called to tell me he's going to Korea for the month. Wonder whether he'll miss me as much as i'm gonna miss him!
I feel like a little girl whenever i talk to him, when am i going to grow up?
