SAHEM62896 saidI don't mean just in terms of your ability to speak another language, here. I am talking about not only your ability to function in another culture and be sensitive to as many layers of it as possible (e.g., gender, generation, geography, status, race, and the periphery), but also your ability to comfortably jump back and forth between two or more different cultures without losing or forgetting too much in the transition.
ummm... not entirely sure what you mean, dear SAHEM. I do think I tend to be a chameleon, thanks to the US Army sending me everywhere, in the US and outside it. One of my private mottos is "Thrive where you are planted" because I have been planted in so many different places, often not of my own choosing, and had to thrive there or perish. You'd be surprised how resourceful & flexible we can be when our options are limited.
As a result I've acquired the ability to enjoy almost every place I find myself. But in answer to your question, neither do I forget or lose anything. Instead I share, with those who are open, like a bee spreading pollen. If you are closed, fine, but I both blend & bring.
So I hope I'm very culturally fluent, at home wherever I go, and still learning even at my age, as I continue to encounter new cultures. And I incorporate it all, still more American than anything, but also being my own version of an American. And that, after all, is what I always thought America was all about.
