As most of you know I do not live over there, but I spent the Christmas in Buenos Aires in 2007.
For me the thing that, absolutely made Christmas was the generosity of, not only the locals but the expats as well.
We were invited to family gatherings, parties and milongas.
The highlight for me was, being an atheist at a Jewish Christmas party in a Catholic country, and nobody asked about my beliefs.
Pure, untarnished, generosity. I miss you all.
