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

And you over think
Always speak
Cryptically

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 and you’re out
You’re up and 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, You don’t really want to stay, no
*but* You, 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 and you’re out
You’re up and 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 your 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

{CHORUS}
