Insightful. Way to go Fran and Gus, that one was indeed a novelty to me.

  I am in Rio too, but I am coming back home Saturday. 

  That is, flying red-eye flight Rio-Campinas-Natal, then going by bus to Joao Pessoa.   This is going to be tiresome.   My wife underwent breast surgery here, then comes radiation therapy  or chemo, all that jazz. 

  That´s why I am a little "out" these days, you guys are doing a good job anyway.
