"Nonviolent / Compassionate Communication" as originated by Dr. Marshall Rosenberg, PhD (Marshall Rosenberg - Wikipedia) includes the following requisite components for genuine communication to happen:

Factual Concurrence (Sam: "Oh, I didn't do the dishes as you asked. Sorry!")

Relatability of Feelings (Glenda: "I feel badly about that. You told me you'd do it, y'know!")

Espousal of Yearnings {needs, values, desires} (Sam: "I know better today that cleanliness is good for overall health so I'll wash these now.")

Tellings & Askings (Glenda: "Thanks! Let's wash it all together." Sam: "Yes, milady.")

If you ever are involved in a conflict or heated argument, be sure to express and achieve the above with whoever you're with somehow (kindly), and generally in the same order as listed above, to safely and efficaciously diffuse anger, dissuade people from threatening others and to make peace.

From Marshall's book 'tis good to also be mindful and present with others (like we would want too).

Of all that I've experienced and done in years of professional service and also with family, friends, and strangers alike the preceeding has helped every time if strictly needed and heeded (so to speak!).
