One more I'll add is to show/say some response, anything. One group of people I've found difficult to interact with is those who won't show any emotion or acknowledgement. It could just be a visual cue, a nod or a smile. I've noticed when the other party doesn't provide any visual cues, we tend to talk more either into hard pressed convincing or make some assumptions to go in depth into it until we get a response. I've noticed that I talk usually more than necessary to someone who is quiet. I've tried being on the other side and have noticed the same behavior from the counter-party. I guess we are hard wired to get some or any response for our contributions.
