llevar (to carry, bear) & traer (to bring)

llevar (to carry, bear) & traer (to bring)
 

I know what the meanings of these words are, but my question is that sometimes they use llevar when I would say bring. What's up with these two words- are they interchangeable?

Thanks,
CH.

For me not ;D ;D
Give us some examples.
For me
traer (Bring) its always to my position
"¿Me traes una Coca-Cola?" (can you bring me a Coke?)
llevar (carry) its always to other position
"¿Me llevas a las estación?" (can you carry me to the station?)

Give us examples and tomisimo will answer ;D ;D.

Saludos
