There was a girl with the toughest of skin
She made sure that everyone around
knew that she wasn't sensitive
She walked around (Ah, ah)
Let nobody in (Ah, ah)
Thought if she'd never gave her heart away
it'd never end up broken

But boy x, across the street, oh, he was one of a kind
Made her fall in love with only just a look in her eyes
When they wandered off
to someone else's for the first time
She cried and cried and cried

Next time you move on
Like I know you do
Tell me you won't treat her like you did with me and you
When she falls hard
And a little too soon
Promise you won't promise things
you know just won't come true
And don't you dare make her feel
like she's the only thing you're seeing, no
Don't do that stupid thing
with your eyes, unless you mean it
When you get bored, like you always do
Tell me that you'll let her go
before you look for someone new

Yeah, this very girl
Brown eyes and blonde ends
Know she never wasted time
but time with him just felt so different
She wrote him songs
Just to watch him listening
A hundred songs, a couple months
No, she never saw it comin'

Next time boy x, across the street
she never see him again
She really thought he was forever
then forever was dead
Left her holdin' up the pieces of her heart by a thread
He left her there to die

Next time you move on
Like I know you do
Tell me you won't treat her
like you did with me and you
When she falls hard
And a little too soon
Promise you won't promise things
you know just won't come true
And don't you dare make her feel
like she's the only thing you're seeing, no
Don't do that stupid thing with your eyes
unless you mean it
When you get bored, like you always do
Tell me that you'll let her go
before you look for someone new

There was a girl
Not too different from me
She thought she found the world
But then the world found out she's weak
Guess that's okay
No, I just couldn't see
That there was a billion of boy x
but babe, there's only one of me
