When your conversation partner is getting angry, the single best thing you can do in most circumstances is to stop whatever else you're doing and listen. It's very difficult to remain angry with someone who is patiently and earnestly listening, and if you break the cycle of frustrating dialogue early by switching to listening and learning, you can halt a great deal of your partner's mounting anger before it starts.
