"The word “listening” in Latin is obedire, and audire means 'listening with great attention.' That is where the word 'obedience' comes from. Jesus is called the obedient one, that means the listener. The Latin word for not listening, being deaf, 'surdus.' If you are absolutely not listening, that is where the word 'absurd' comes from. So it might be interesting to note that somebody who is not listening is leading an absurd life."
