Gratification

I want it now!
They were heard to say.
Not a thought of how,
Was offered, nay.

Only demand,
With loud protest!
Again remand,
Who dares molest?

They oft consume;
What isn't theirs.
Depletion looms,
The loss of heirs.

Nothing is left,
Benefactor replies,
You've squandered your gift,
Your inheritance dies.
