Interesting topic.
I get where the OP is coming from (pun sort of intended).
Getting asked where you're from constantly by literally everyone you meet is tiring. And it's often followed by a comment on your English speaking skills. And some cliché about your home country.
Now, I'm French, and trust me, I always get the GCSE exam speech after a few minutes: "Je m'appelle John Smith, j'ai 14 ans, je habite l'Angleterre...". Cool story, bro.
(By the way, it's "J'habite en Angleterre" ;) )
Even at social events, with friends (like dinner parties etc.), these conversations are tiring, because they're always the same and never go further than :
"Where are you from ? Where exactly ? I've never been there, but I've been to Paris. It's great / It's shit. Why did you move here? What do you do now? [GCSE Exam speech] OK, I need to talk to other people now."
These kind of "conversations" make you feel like the only interesting thing about yourself is your home country. Once that question is answered, there's nothing left.
Now, I'm not against chatting about my culture and stuff, I actually quite like it. But then, be ready to sit with me and have a proper chat with me. Don't ditch me as soon as your questions have been answered.
(I'm using a general "you", not directed at anyone in particular.)
