Polonius gives Ophelia her blocking. What sort of director is he? Does he just point to the location he wants her to walk in? Does he demonstrate for her the manner in which she should walk? Is he specific about this location or general? That is, does he point, with a finger or hand or just give a bit of a wave in some direction or other?
Polonius does have some experience in the theatre. He did play Julius Caesar that time. Is he orchestrating another great play here?
