I’ve been noticing this in professional sports—when Brazilians play (either as individual members of a team, or as a Brazilian national team), the names on the back of their jerseys are their first names, not their last names, as is usually customary. And I noticed while watching pro volleyball on ESPN, all the teams from other countries were officially referred to in the scores, etc, by their last names (ie Walsh-Mays) while the Brazilians were referred to by their first names (Eliana-Gisele). What’s that about?
