People do not know how to act around mixed heritage people

I understand how you could come to feel this way, and there was a thread about this previously, and no doubt you are precisely correct about some of the people you hear it from.

But I can also say, with absolute certainty, that “where are you from” is nothing of the sort to a lot of people. White Americans ask each other this all the time, at least in my cultural context. It’s akin to the “demand” to know the name of the person one is speaking with. (Do you get tired of people constantly insisting on knowing your name?)

And again, when I ask where you’re from, that really is what I want to know. I want to know the place that you (not your parents) grew up.
