An example of what I mean:
I, in China, told an English speaking Chinese friend I needed to stop off in the bathroom to “take a shit.”
He looked appalled and after I asked why he had that look, he asked what I was going to do with someone’s shit.
I had not laughed so hard in a while, and it totally makes sense.
I explained it was an expression for pooping, and he comes back with, “wouldn’t that be giving a shit?”
I then got to explain that to give a shit means you care and I realized how fucked some of our expressions are.
What misunderstandings made you laugh?
It was actually nonverbal - I didn’t understand the so-called “Indian head wag.” Working with a lot of programmers from India, I was often faced with that sort of gyrating head gesture while explaining something. To me as an American it kind of means well yeah sort of, or okay but not really - but in India it indicates understanding, like a simple head nod in America. I couldn’t figure out why so many people seemed to think I was being unclear. I would repeat things or say them in a different way, and sometimes they would do the head gyration even more - turned out they were just saying okay.
