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 good for me 

'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 wanna stay, no
You, but you don't really wanna go, oh

Someone call the doctor
Got a case of a love bipolar
Stuck on a rollercoaster
Can't get off this ride

You change your mind
Like a girl changes clothes 

'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, down, down, down...
