I really like these lyrics. Reminds me of something, although I can't quite place exactly what.. I hope I'm not boring.

---
You change your mind
Like a girl changes clothes
Yeah you, PMS
Like a bitch
I would know

And you over think
Always speak
Critically

I should know
That you're no good for me

{CHORUS}
Cause you're hot then you're cold
You're yes then you're no
You're in then you're out
You're up then you're down
You're wrong when it's right
It's black and it's white
We fight, we break up
We kiss, we make up
You don't really want to stay, no
But you don't really want to go-o
You're hot then you're cold
You're yes then you're no
You're in then you're out
You're up then you're down

We used to be
Just like twins
So in sync
The same energy
Now's a dead battery
Used to laugh bout nothing
Now you're plain boring

I should know that
you're not gonna change

{CHORUS}

Someone call the doctor
Got a case of a love bi-polar
Stuck on a roller coaster
Can't get off this ride


You change your mind
Like a girl changes clothes..
