""El viejo adversario le dice adiós a un amigo." ("The old adversary bids farewell to a friend.") - Said in 1974 by former head of the UCR, Ricardo Balbín at Juan Domingo Perón's funeral. Balbín had been Perón's biggest enemy during their political careers, but the phrase symbolizes how, despite their enmity Balbín was respectful enough of his adversary to solemnly attend his funeral."
