Face his room, his car, his seat, or the general direction you think he is located and, with absolute conviction and all the anger and hate you can muster, gesture lewdly. Give the finger. Fly the bird. Make a face. Stick out your tongue. Thrust whatever you want in his direction. What an outlet. It always gives me a rush of satisfaction, makes me feel brazen and not the compliant woman waiting, waiting, waiting for things to happen.
Maybe you can add a voodoo sound to the mix.
