First I'm sorry to disturb, but I am a writer in my language and in need of a native American-English Speaker, so as a long time silent reader here I thought it's good to register here.
It's about the following conversation:

Bryan: But they are not the same then.
Cathy: No they aren´t.

The "no" confuses me. So I ask myself what Cathy want's to say with her answer:
a) That's wrong. In my opinion they are the same.
I agree, They are not the same

Where's Ghoti when you need him?

Cathy's "no" is an affirmation of Bryan's statement.  She's agreeing with him, that they are not the same.

@Jrob78 puts it best.

Should be a comma between 'no' and 'they'

No, they are not.

or as bigbill would say

or are they

Cathy is a woman, only Cathy knows what she means and you absolutely CANNOT argue with Cathy because Cathy is a woman and she thinks she is always right.

In my best native American English, "How", which means hello, or at least it did in all the westerns I saw when I was a kid.

Are Bryan and Cathy talking about plastic worms?  If so, then yes, they are not all the same.  I think you should check with Gary Yamamoto.  He has made and sold more plastic worms than anyone else.

Hope this helps.

English is a strange language.  There are all sorts of rules regarding the proper use of English.  The problem is, there are exceptions to every rule.

For example, in spelling, the rule is "I" before "E", except after "C", or when the word is pronounced with a long "A" as in sleigh or weigh, or when the word is seize or siege.  The ei or ie is pronounced as a long "E". 

See what I mean?

I think the "aren't" is the tell in agreement with jrob78.  

Using "are" would have meant the opposite.

If she had just said "no" with no qualification,  it would have been considered more ambiguous and in need of clarification.

 

And oh,  welcome aboard.

No means no.....

... in need of a native American-English Speaker,

Dylan, not trying to confuse, but there is not one native American English language. There are many dialects.

I am from the South so we use words, slang, and verbiage that would leave people from California and New York scratching their heads!

So all across America is a variety of dialects and no two are alike! And then there is ebonics... and as stated the language of woman. You know- when she says yes, she really means no, and when she says no, she really means yes! 

Some things just are not meant to be figured out!

Oh wait, when you say native do you mean Native? As in Native Indian? OK, maybe I am getting confusing! 

What they said above... go with it!

Fun thread. By which I mean I am enjoying the exchange of ideas, not like the fun of  pulling the thread to open a bag of dog food! 

I agree with A-Jay that one can learn much about language and fishing vernacular here. Whether it is of any value in a discussion of the proper use of English is questionable. As buzzed bait mentions, with the advent of texting and internet speak, written language, if not dead is certainly on life-support. 

Thank you all for your warm welcome.

So just to understand you right (sry for my mistake English), you also think like jrob78 that when Cathy says " No they aren´t." she agrees with Bryans statement that they are not the same?

Cathy is responding twice to bryan. She is saying no, then she says they arent, arent being a contraction for are not. She could have used just one of the phrases to answer.

Yes, she means they are not the same.

And they say English is easy..

You also cannot forget "Any luck?", "Catch any?", "Are you on fish?"

Whooda thunk their r sew manny cmart peepull hear

Isn't it spelt Kathy? 

Cathy is using a double negative to affirm Bryan's statement. 

Don't ever not use a double negative.

 "My darn rod broke"

dang, dagummit, dangnabbit, dependin on what fer part of the kuntry you liv in... 

It depends what they are talking about 

Cathy is very confusing. A better response from her would have been "Correct, they are not the same."

Not sure that would ever happen because she would have to admit Bryan is right in his statement and we all know a woman will never let you know you are right!!!
