Yeah. It's the cake Analogy.
You have a cake, in all of it's glory.
A woman comes and demands a piece of the cake. You give in, after all there's a lot of cake left.
She demands another piece. You still rationalize that there's still plenty of cake.
And before you know it. You only have one piece of the original cake while the woman is fat and bloated. Demanding that you give up the last piece of your cake.
