. I read something not so long ago - feel sure it was here. Character A's POV. He utters some dialogue. Character B wonders what he meant by it (or felt - another word choice to suggest inside the head). Character B wondering was a shift in POV - it was a view inside B's head. I felt that pondering was also inside the head, hence the question if it was a POV shift. Agreed.
. My bold. That has aided a lot in understanding. Cheers. I've looked at countless sites that explain POV, but exceptionally few give anywhere near even basic examples.
