My name, following Spanish uses, is "Juan Manuel" (name) "Barranquero Ríos"
(two surnames).
It's uncommon here to refer to someone by the two surnames, other than in
specific
situations. And I don't like my double name, so I *always* use Juanma,
except in official
documents. I introduce myself as Juanma Barranquero and that's how I
self-identify.

...Except that I went to Buenos Aires, coming from São Paulo, and I don't
know what did
the travel agency assume about my origins. All I know is that I was in a
hotel lobby and
suddenly they called for a "Mr. Juan Ríos" and I thought for a moment
"curious, that guy's
got the same name as my maternal grandfather"... Until it dawned on me, a
few seconds
later, that *I* was supposed to be "Mr. Juan Ríos".
