@mark noble,
Yes, but I wanted to get the meaning of Cathys "No they aren't" in this context:
Bryan: Okay, I always need to think about that person on the picture, who I thought was your friend. But they are not the same then.
Cathy: No they aren't
And there she agrees with Bryan that they are not the same, like Glennn said, correct?
So all in all Cathys "No they aren't" = "No, I agree, they are not the same", correct?
