I can speak Spanish, but learned it from growing up in Haiti, so I'm not very fluent right now, although it comes back to me rather quickly.

I also spoke Creole and French in Haiti, since the west side of the island speaks those languages.

Right now I speak Thai the most, since I've been living in Thailand since 2010.

But if you are looking for someone who grew up in a Latin culture, that's not me. My parents were American missionaries, so I got US Caucasian culture, alongside French/African culture, with many Domican Republican friends, who spoke Spanish.

I also taught for one semester in Hermosillo, MX, in 2001, and was fluent in Spanish during that time.

Probably lots but I am not one of those. How about Swedish? Both start with S.
