Different names for the same thing

So Death Cab for Cutie has a song I am currently into right now (several actually) and the title is "Different names for the same thing". (They have quite a cool movie with little videos from various directors ... I think the title is Directions...) I was listening to it last night and was thinking of all the words/names I have been learning here in Guanajuato. And sometimes I feel constricted because I cannot think of a word in Spanish ... and I like words very much.

But then as I listened some more I began to think of how we say lots of things underneath our spoken words. Some of the things I have heard lately in conversations with new friends and new people in GTO:
-- Uno cada dia..
-- I am still trying to figure out exactly what I think about things... I am just not quite sure about who I want to be yet, but talking helps me figure it out.
-- Well, my husband is a lawyer..
-- Yes, but our son lives in the U.S. ... it is very far.
-- Did they just say I am a "blanco gigante" and start laughing??
-- Don't tell _______ you saw me here...
-- Whatever...

Are they all different words for the same things? Perhaps. Which is another reason I love travelling... it helps me open my eyes and ears more so I can hear more clearly.
