Era terribile andare in giro con lui

…. He was able to start a conversation with anyone….
Marcello MarcelloNOT Marcello
I am not still angry……
My r
eg
ret
... Durante l’ultimo periodo, Marcello era un pò arrabbiato con me … ancora oggi non ne conosco il vero
motivo. Lo avevo invitato piu volte a prendere un caffè insieme, per capire. Ma lui aveva (molto signorilmente)
declinato. Alla fine avevo deciso di non insistere, e di aspettare il tempo di cui aveva bisogno per perdonarmi e
spiegarmi…… ma purtroppo questo tempo non ce lo abbiamo avuto.
Anche io mi ero arrabbiato con lui! Ma voglio dirgli che ora non lo sono più!
During the last period, I realized that he was little bit
angry with me. I never understood the motivation
and he did not explain me. I tried to take a coffee
with him in order to speak about it, but he declined
(always in a very polite way). I finally decided to not
make pressure on him and to allow him to
take his time. But, unfortunately this time was not
allowed. I was also angry with him!
But I would like to say that I am not still angry
with him NOW!

Giornata per Marcello, Roma 09 Dec 2014 Francesco Petrini
Un caro ringraziamento a MARCELLO CIAMPOLI,
che mi ha insegnato veramente tanto sulla ricerca ma che, soprattutto,
mi ha insegnato che non bisogna mai prendersi troppo sul serio.
I would like to give my acnowledgments to Marcello Ciampoli He taught me
many things regarding the scientific research, but the most valuable of
these is the importance of not taking myself too seriously
