Sixes and sevens

Good heavens
and here you are at sixes and sevens
can't I mean anything good for you?
again and again you've been untrue

such is embedded in your genes
apparantly so it seems
once more my dreams are shattered
your betrayal has been all that mattered

you can shag up with your lover
you'll find some new stuff to discover
don't come runnin' back when things don't work out
you're a fake that's what it's all about.
