I don't remember the last time someone asked me where I'm from but they all feel the same. It's usually in a work setting or when I'm at a party / out.
A lot of the time they ask me what my nationality is, to which I calmly say back: Australian. Obviously that isn't the ‘right’ answer, but they aren't asking the right question, and it's clear what they want out of it.
It's clear they just see me for my skin colour and being exotic. It used to make me feel isolated and seen for the wrong reasons. But because of how repeatedly I get asked this my response is automated and comfortable.
If they ask respectfully about what my ethnic-background is, I'll give them the proper answer that ‘my parents were born in Sri Lanka but then moved New Zealand where I was born but I moved to Australia when I was five and grew up in a regional town in North Queensland.
