Language Learning

I will never understand how anyone can think there is no value in learning a second language. While speaking several languages is obviously more useful for some people than others (e.g., people who travel a lot, or work for a multinational company), it’s not as if speaking a second language is a total waste if you’re not one of them. There are so many advantages to language learning; I just wish everyone could see them. My family, for example, used to say stuff like “why are you learning French? We speak English in the US!” They just didn’t get it. It’s a little better now, since I obviously use French and Spanish for work, but they still don’t have any idea about why I find language so fascinating.

What do you think? Am I missing some obvious argument *against* learning another language (other than a simple lack of time)?
