PARABOLIC....

“Once, a long time ago, I was walking with my father when at a bend he suddenly stopped. After a moment of silence, he asked me:

 – Besides the chirping of birds, do you hear anything else?

 I sharpened my hearing and, after a few seconds, answered.

 - I hear the noise of a cart...

 - Right, said my father.

 It's an empty cart.

 I asked him:

 – How do you know it's an empty cart if we can't see it yet?

 And he answered me:

 - It's very easy to tell when a cart is empty, it's because of the noise.

 The emptier it is, the louder it hums and makes more noise.

 Today, as an adult, when I see a person who talks a lot, interrupts other people's conversations, proves himself to be inappropriate, brags about what he has, feels powerful and despises those around him, it still seems to me that I still hear my father's voice saying:

 "The emptier the cart, the more noise it makes."
