Dear Ferran, we will remember these hours in front of the blackboard in Barcelona, we will remember your powers of perception and your enthusiasm about mathematics.
We will remember our discussions about wines, about "polar français", which you knew better than us, about saying "quatre heures moins le quart" in many languages...
We will remember that when Monique was preparing her latest visit to your group, you wrote "J'ai déjà placé dans la cave un verdejo Rueda spécial.", you could still remember that she had liked that wine, which you had made her discover many years before.
We will remember so many good moments with you.
Paraphrasing famous lyrics:
"Ferran, cent ans après, coquin de sort, tu manqueras encore."
Monique & Olivier
