I wish I was fluent in another language, too. I have the aptitude, but unless I'm immersed at this point, it's not going to happen. I can get by in Spanish, for traveling purposes, but verbs make all the learning go out the window when I'm trying to speak under stress. And now, because Spanish is the one language I am just a little familiar with, when I try to learn a little of another, I keep thinking in Spanish. I marvel at those who speak multiple languages. I have one son who is fluent in Italian (he lived there for half a year) and my younger son came back from his first deployment in Spain a few years ago, speaking rapid and fluent Spanish. He now can handle a bit of Farsi and Pashtun and is taking Chinese in college.
Sometimes, I feel utterly talentless.
