I am the instigator

I'm really not the nicest guy
When it comes to playing fair,
I'd rather your woes multiply
Than take my honest share.

Whilst you are sat there, weeping
I'll look through you like you're hollow,
My insidiousness is creeping,
Makes this hard for you to swallow.

It was always going to end like this
And I was always set to win,
You fell for my deceitful kiss,
Which made you blind to constant sin.

I found the lying easiest,
When I wore a gormless smile
That's when I'm at my sleaziest,
Playing happy families for a while.

So, I'm leaving now, because I'm free;
Take a good, long look and then,
No sight, no sound, no hint of me
Will come your way again.
