@CryptoSharon Thanks for your comment, I had the same thought. I used google translate to translate the replies in Spanish. 

In Person, people often assume that I am Latino. But like President Obama, I am Black & White (Irish Mom). None of my Ancestry is Latino at all.

In real Life when People launch into Spanish when speaking to me. I just repeatedly reply Que? with a quizzical look, I keep repeating it with each Spanish reply I respond with Que? Until the realize that I am not Latino OR they just think I am mental! LOL ;)
