I've noticed something that goes on whenever someone is asked about their heritage, people never say "American" or anything like that despite being born in the US (even if every living ancestor was born here as well). Everyone will say "50% this and 50% that" instead. I'm curious as to if this is something that goes on everywhere or is it specific to America because it seems cool to be descendant from people who are from some far off nation. Or the fact that the US is a relatively new country and peoples ancestors can be tracked more easily or somesuch.
