You are the director. In the movies, rarely is a scene shot straight on. The camera is usually at an angle or pans around the characters. As a writer, you can simulate these dynamics. Rarely are characters alone in a scene without a phone, a knife, something.
People talk with their hands and bodies as much or more than their mouths.
Not a word has been said, but a message has been sent. This kind of indirection is an extremely valuable tool for effective and stylish storytelling. Make props a part of the scene. Motion is good. Next, tag the characters themselves.
