I am trying to focus and digest what you wrote for 2 articles. When I am down with flu cough and viral fever 6 days straight, it is pretty difficult to concentrate on reading. But, here I remember at the end of your article about the piano. The black and white keys are what make the music beautiful, and life is the same. We need the good and bad. Alberto, please lit a candle for me and say some prayers of peace for me. Thank you.
