It makes me instantly panic when people ask me where I'm from, especially if they just want a quick answer. I don't have one.
It's frustrating not knowing what they're asking for, and yet not wanting to take up more of their time by asking for clarification. Birthplace? Ethnicity? Nationality? Residence? Languages? Culture? Those are different, nuanced answers.
But mostly, being asked to choose just ONE part of me is really suffocating.
