Watch what you say

On our wayto Washington D.C. my friends and I (no one was American) ("my friends and me" would be wrong in this case, because you ask for the subject. I´m pretty sure the way I do it is right.) wondered in what state Washigton D.C. is in. So at a stop at a gas station we asked the woman, who worked there. her answer: "Oh boy, you gotta stay in school!".
Nice, so if you don´t know that, you better stay in school. So we told her taht we weren´t from the U.S. and what did she say?!

"Doesn´t matter where you´re from!"

Wow, so it doesn´t matter where you´re from, every one around the world has to know that Washington D.C. is not in any state, it´s in the District of Colombia?!
It craped us up. It was about the funniest thing I´ve heard in a long time.

Sometime you should really start thinging before you speak it out loud. But any help for this lady was too late anyway. She did not even get it after everyone had to start laughing.
