Did you ever go to the IHES during the Grothendieck's time?

Connes
Not at that time mostly because from the distance it looked like such an arro-
gand group. After all these years Ⅰ finally took the time to read grothendieck's
book recoltes et semailles and this allowed me to really understand his per-
sonality much better.
