Acting over the shoulder

What I call "acting over the shoulder" is a typical symptom of bad acting. The actor’s lines are like orphans. Abandoned. They don’t connect. There is no will to influence. They sail past their intended target, flying over their partner’s shoulder to expire somewhere in the wings of the theatre. The actor should instead speak to his partner, trying to change him. He should feel his own words as active sense organs, exploring the contours of his partner’s personality.
