The Case of Joachim
In 3 months moving from no knowledge to almost speaking Spanish fluently and, as mentioned, all picked up during the 3 months he lived in Havana.
"The first victory we can claim is that our hearts are free of hatred. Hence we say to those who persecute us and who try to dominate us: ‘You are my brother. I do not hate you, but you are not going to dominate me by fear. I do not wish to impose my truth, nor do I wish you to impose yours on me. We are going to seek the truth together’. THIS IS THE LIBERATION WHICH WE ARE PROCLAIMING."
Oswaldo José Payá Sardiñas (2002)
