Why don´t they understand me?!

Here is my question: Why can I go into Piura or travel to Lima, even Ecquador, and people understand me just fine, but then I am in site and no one has any idea of what I am saying! Agh, its so frustrating! No wonder I am so self consious about my spanish. Its because people in my site make me feel like I am bajo bajo. They make me feel like I know nothing! And trust me, there is nothing more frustrating than not being able to communicate. And there isnt a bigger insult than when they tell you your friend´s spanish is better than yours. They are trying to insult you, they are just being honest. Its like the whole thing where they call bigger people ¨gordo/a¨ and thinner people ¨flaco/a¨. Its not an insult, thats just what they do in their culture. But us Americans do take it as insult, or not as lightly as we should.

Like i was with my friend the other weekend and we met this guy that worked at this restaurant. He was talking to me and my friend and then later asked if I wanted to go out and get ice cream. I was like sure, that´ll be cool. So then he goes on to say ¨Your friend speaks better spanish than you, doesnt she?¨ WHAT! You just ask me to go out on a little ¨date¨ and then go on to insult me and tell me my friend is better/smarter than me. Yes, that is something to tell a lady when you just asked her out!
