Re: "you don't look pakistani!"
Afshi you probably get the arab comments because of your scarf. I get that too, I had one woman asking me if I was Palestinian and when I told her I was Pakistani she was disappointed. lol.
I've also had people thinking im Turkish, Bengali (why?). actually it also depends on the area you go to if it is where there is a certain minority, they'll tend to think you're their kind.
