I'd suggest a good movie to help expose blindspots regarding "all those Mexicans".
A Day Without a Mexican. In South America, we get some interesting questions:
*So, it's hot and humid there, year 'round?
Answer: No, we live at 10,000 ft; it's more like 40-70°F year 'round
*So, do you like tacos and beans?
Answer: No, you're thinking Tex-Mex. We actually like soups with 3 different kinds of potatoes, chicken and rice and mondongo

*Spain: "You realize you don't actually speak Spanish in Latin America"?
Answer: What an embe(th)il!
The "roundabout"s are called "redondels" (from redondo=round). Colombia calls them "rompoys".
We turn left on red lights, and hardly ever stop for one from 1 a.m to first light.
I hope this thread will not turn into a flaming war, but will help all of us to appreciate "different" as just "different", no more.
