Dear Francesco,

I do not think the discussion was very overheated and I actually enjoy my exchanges with Mattesini. We are both probably too stubborn for our own good! :-)
I think we can devote our attention to other topics since this one will not be solved by us at least not in the immediate future. I have tried to leave it aside by Mattesini seems bent on getting me to change my mind!

All the best,

Platon

P.S. I know understand better Mr. Bargoni's reaction! :-)
