As Thick as Thieves

I've told you before
It don't mean a thing
So you knock on my door
I tell you I'm not in
There's nothing to do again
Except climb on that roof and then
We end up in A&E
With more than a bruise or three

We have trouble in mind
We live by deceit
We don't play by the rules
Cos We're as thick as thieves

I've seen you before
But nothing to mention
I realise right now
You've got my attention
The way that you look at me
And acting so seriously
You know that I'm with someone
That's never easily undone
