When thou writest a POINT OF VIEW, thou shalt NOT change the POV in the middle of the scene. If thou dost, thou shalt have a VERY GOOD reason for doing so, yea and verily the reason must be JUST and the use of the POV shift must be RARE. Two shalt be the limit of thy POV shifts, and the number of the shifts shalt be two. Three shalt thou not shift the POV. Four is right out.
