My life with GianCarlo Ghirardi, a great friend, a great teacher and a great physicist

In these shorts notes I want to remembermy relationship with GianCarlo Ghirardi, who was my supervisor in my Master Degree in Physics at the University of Trieste and then he became a very deep and close friend. I don't want to describe in details his scientific steps in the world of modern Physics: many others will make better than me. I want only to share which was my relationship with him as a teacher, a man, and expecially as a deep friend, for more than 40 years.
