What does Buddhism say about how to manage other people's anger? Does Buddhism suggest any specific attitude when we are facing angry people, especially when they are unable to control their anger and/or unaware of their anger? Intuitively I try for example to listen to the person, understand him/her and remain calm myself as much as possible. What kind of recommendations or advice does Buddhism offer to help us in such situations?
