What if I was pleasantly surprised and thanked her?
That's nice. Were her comments believable?
I may or may not believe her, but I'm still surprised and grateful to be given such a good comment.
It sounds like a pleasant situation all around. It's nice to be appreciative of kind comments.
Maybe she was just being nice and doesn't really believe that about me.
Even if she was just trying to be nice, it is good that you thanked her for what she did for you. It will make her more willing to be nice to you in the future.
