Indian: Hey are you Indian?

Re: Indian: Hey are you Indian?

Yes you are right I used to get this remark too. On a positive note their remark is not because they want to insult you it is because they want to find a common ground. But being Pakistani I also want to be identified with Pakistan distinctly and clearly so I invented an answer , read on.
My answer has been :
I am from that part of India which is no more India, I am from Pakistan.
This answer does not leave the room for any other kind of remark.
Nobody took any offence so far so I think this answer works. Unless someone comes up with a better one.
