In this picture all my nostalgy for the old days, when I sent a fake mail from our supervisor to my co-students, “you should come to my office now”. I still see their worried silent faces trasnform into a loud laugh at the sight of the little childish fish I had put on the door of the supervisor. Being 28 years old I was rather nerd, yes. Each 1st April I miss that moment, my co-students, and Polito.
