Some people are there speaking Spanish as a second language so you can eventually distinguish accents from other countries as well. The first time this happened to me is when I was at a Chinese Restaurant in Floresta Argentina. Imagine looking at someone who is obviously Asian who is speaking Spanish with a Chinese accent. It is a little confusing to say the least. You do realize that there is a difference in the Spanish speaking.
People can tell.
But what if you spoke with someone who didn't have a recognizable accent. We often don't think about it, because if we understand them that is all that matters. Sometimes we can tell what part of the world they are from, sometimes they can speak to us and sound as if they were born and raised in the Midwest. The reason I bring all of this up is because I need to prepare you for a remarkable story. A story that may be proof that extra-terrestrials come and go here all the time.
