I've had a lot of really interesting conversations about the power of language while I've been here (kind of a given, as I'm learning one). What I think is so interesting is how the language you use effects how you express yourself: for instance, I think speaking spanish comes with a higher level of- what's a good word to describe it- drama(?) than other languages. At least for me, I feel more dramatic when I speak spanish...the inflections of my words are more pronounced and strong. I'm also coming from Texas and we talk pretty damn slow so there's a big difference in the first place...but still, it's an interesting thing to think about.
So for those interested, check out this NY Times article, it's pretty interesting:
