I'm an American, so none. I did try Spanish once. I got the syntax down, but the words and conjugating the verbs confused me. I want to try again. (Still, I feel people who live in the United States should learn English. You come here, you adapt to us. We go there, we adapt to you.)

When I travel abroad, if someone doesn't speak English, I just try again slower and louder.
LOL. Not really. If I don't know the language or do not have an interpreter, I won't visit the country, because its my job to learn your language in your country.
