Do people ever think your a different ethnicity then you actually are?

I'm 100% Armenian, well actually I'm Armenian-American, and most people think I am spanish and the other guesses have been :Italian, Iranian, Hawaiian, Philipino, seriously how can I look like all of these things when NONE of these ethnicities look alike and the only reason why someone asked me if I'm Hawaiian is because they think I look like Lilo, from Lilo and Stitch, which I DON'T and it's annoying how people ume and don't ask me, I look Armenian, I look like my relatives so I KNOW I don't look anything other than what I am
