I thank Ricardo and Nuno for inviting me to ECB's xmas party! It was a great excuse for taking Z-A to Frankfurt! Following the original idea from Nina and Lisa - several months ago - finally there was a good timing for travelling to Germany... Even if everybody was very busy at this point, Ricardo took control of the situation and contacted Club Voltaire - thank you for making it possible! The staff was very nice and very professional. I thank Lisa for being a great host, Diogo for the collage and Pico for overviewing the text. I send a big thanks to all of those who made part of a very nice xmas-mood-weekend in Frankfurt.
