Without fail, once a week, someone asks me where I'm from.
"Hey, where are you from?"
"No, I mean, where are you really from?"
Sometimes they'll clarify with a "from Africa," and every time I'll say, "My family has been here for a long time, no one is from Africa." It's never not annoying, and sometimes—when there's an undertone of "you don't belong here"—it's racist. But most of the time, it's just annoying.
