We probably are sort of lazy with language, but I don't think we really need to know more than one. There are some circumstances that you may need to know a foreign language, but I guess it just depends on where you live. There really aren't many people around where I live that don't speak English, but for others on here it's probably different. I am taking Spanish class, though, not because I want to learn the language, but because you have to take 1 or 2 years of foreign language to go to college, and I want to get it over with.
