After 8.3 years of Spanish lessons, in a family of francophiles, Mexico is a bit of a challenge. People always expect you to talk to the locals, who are actually fluent in English.
But on the bright side, I've gotten very good at saying when asked, "Oh, hablas espanol?" "A little" (un pocco) and also "Every time we come to Mexico my fill in the blank thinks i am better than i actually am"
But when I say that, I'm pretty sure that my grammar is incorrect.
