¿Cómo sé? [English translation]

How do I know if what you say is true

- [i don't know how translate the second line, sorry]

but from a long time ago i got the feeling

that something yells and says "this is not like that,

it could be another way"

The thing is not like that

Who do you think you are?

How do I know that if you smile

means that we know each shoulder very fine

but from a long time ago i got the feeling

that when you look at me like that

there's something left quiet.

It could be more simple,

this is not the way we planned

Who do you think you are?

It doesn't matter anymore

That you don't like

the way I say

Here you have it

It doesn't matter anymore

That you don't remember

I already told you

There you have it

It could be more simple,

this is not the way we planned

Who do you think you are?

It doesn't matter anymore

That you don't like

the way I say

Here you have it

It doesn't matter anymore

That you don't remember

I already told you

There you have it

P.S. It could be a better translation, but i don't speak enough english
