Hopping on here after being flooded with discourse on my tl to say that I agree, we don't know what she meant, and in any case it is not right to jump to conclusions. That's the problem with words, they can be interpreted differently by how you are currently looking at them -
I didn’t like carrie ann’s criticism but I don’t think this is what she meant. I think do she meant “we can see every muscle” as positive feedback.
