WebBut also a deleted neighborhood around p of radius > 0 does not contain points in both A and A^c. So the exterior is out of the question, but I can't seem to place p in the interior or in the boundary. Interior is defined with a neighborhood and boundary is defined with a deleted neighborhood and that is what seems to be the issue.
