Yeah, in fact I edited the conversation for the forum, so I don't need to tell the whole story. My father's name is Roger.
That is the real conversation:
Me (sending a low resolution photo): Is that an old photo of your friend?
Me (sending a higher resolution of the photo): I always think about my Roger. But they are not the same then.
Cathy (looks closer, as the photo is now high resolution): No they aren't.
Does now Cathy's last statement "no they aren't" make sense to you?
a) "No, (I was wrong), they are the same (person)."
b) " No, they are not the same (person). "
