Now I will tell you a very short story. Several years ago a friend of mine told me a story. In his country was mandatory military service. So he joined the military unit where together with other soldiers were to serve the country. My friend had university studies and was placed in a special troupe. But the group's instructor was a guy who had only secondary education. And he was very proud of it. Throughout this period of military service, daily, corporal tried to humiliate "smart guys with university education".
Military service was over, my friend is very good, has a firm, beautiful family etc. Corporal remained the same ruffian with limited views.
