In Brazil, they speak Portuguese. In Argentina, they speak Spanish. Believe me, it is not the Spanish you learned in school.
Actually I’m proud to say in school I failed French for two years. Prissy ass language. The little bit of Spanish I do know I learned in night class. I didn’t fail at it but I hated it. My wife said ‘’If you’re going to fight the enemy you have to know the enemy’’. I think of all the Romance languages Italian is the nicest sounding.
