We couldn't help laughing...

After discussing long with Mr. Alfredo Robbiati, Franco and I decided to show him the patents his father registered. I think we couldn't help laughing at his astonished face and puzzled expression... something he surely didn't expect... but we neither!!! He looked like he was trying to make sense of something... we ensured him several time he was reading right ... and after a furtive smile and a shake of head, the final verdict fell: "i don't remember". Unforgettable.
