'Tis a fact of life and facts of life can be hard
You give some people and inch and they will take a yard
They always do take far more than they are due
That greed begets greed happens for to be true
With their type it is never live and let live
They always do take far more than they do give
You give some people a yard and they do take a mile
They know how to cover deception by guile
Their three special people are me, myself and I
And that's how they will be 'til the day that they die
They leave others to live in financial hell
But karma it surely will not serve them well
Yet sad to say some even their praises do sing
But not everyone is like them which is a good thing.
