The best disagreement I ever had in my life was with a woman that even today is my wife. It passed thirty one years ago, in one small city called Louvain la Neuve, on Belgium. I was just arrived to study in the sociology faculty on campus. One of my first nights in city I went at a little bar called Tio Conejo, owned by a peruvian guy. He asked me for some salsa music for share. I went to my room and carried a couple of tapes of cuban son. But, when I arrived newly, the peruvian was not here. I was attended for a colombian girl with caribean accent. She told me that in this bar people only listened authentic salsa. And she never had knew about someone like Matamoros or Orquesta Aragon. I could not change her mind. I was so angry that I leaved loudly the local. Some days after, I found her at the sports center. I was still angry, but she smile me so kindly that I knew that she was only flirting. So I keep my revenge for later. But this is another history that I will tell you some day.
