Also we learned to sing the national anthem of our host country, El Salvador: "De la paz en la dicha suprema, siempre noble fue El Salvador, fue obtenerla su eterno progreso, conservarla en su gloria mayor" or something similar to that, which is to say: From the peace in the supreme happiness, the always noble El Salvador strove to obtain eternal progress and to conserve its greatest glory" of something similar to that.
