I should know
That you're no good for me.
'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.
