"Most migrants learn and become disguises".
Oh, I think we all do, we learn many of them in our lives. It may seem clearer in the Immigrant space, that feeling of Huxley's "Oh Brave New Word!" where all at once everything is sort of similar, and yet everything is profoundly different.
I spent years where I would get up in the morning, walk down a big nightclub street and see the aftermath, have a cup of coffee at a little old Italian cafe, then walk across the street into SF's Chinatown and feel like I left the planet. You're different and you know it. You can't hide - even at five-nine you stand out in that crowd. You don't speak the same language. Hell, they are not even speaking the same language with two very different kinds of Chinese going down, but you understand neither. And those live animals going into the food stores? Yikes. In Safeway world we're pretty protected from seeing our dinner killed, but in other places, you betcha, that's what I call fresh! I saw a women kill a chicken getting on to a bus one day. And the smells are different, the BokChoy, the 1000 year old eggs, fish for miles.
But you have other mornings where you see that the kids are all playing kid type stuff, and that's no different. Even if you can't understand the words, you know when people are mad at each other, or happy to be talking to each other, and you pick up on that. And even if the products are somewhat different, shopping for food is a commercial deal, and that's pretty consistent around the world. Deliveries are just deliveries, and some of that strange food is pretty darn tasty? Who knew that a culture thousands and thousands and thousands of unbroken (no dark ages in China) years old might invent some pretty good eats? Hell, I even got uses to the BokChoy.
And, little by little you become a part of it rather than being apart from it. I'd be reminded once in a while, when I would be going thought there with someone who was not used to it. Trying to remember how it was when I first saw it. And trying to understand how I was thinking about it now. How it had become a part of me.
You slowly merge with all of it, it changes you and you change with it.
I think its like that with most things.
