"Nonviolent / Compassionate Communication" was originated by Dr. Marshall Rosenberg, PhD (Marshall Rosenberg - Wikipedia)

It includes four types of communication.

He used the words "observances", "feelings", "needs" and "requests" in a catch-all manner:

What procedes is a brief, hypothetical story show-casing "NVC" (which again, is abbreviation for  "Non-Violent Communication" and I also like 'Nice, Very, Communication' as a tongue-in-cheek way to say quite the same):


"Observances" (Experiential Statements):
 

Gloria: "Sammy, the dishes aren't clean and I asked you to do this yesterday."

Sammy:
"Oh, I become very busy and distracted. I apologize."


"Feelings" (Emotional or Sensory Statements): 

Gloria: "Okay. I am feeling badly, however. You told me you would and you've never broken a promise like that since I've known you."

Sammy: "
I feel bad also, Gloria. May I try to make it up to you?"

"Needs" (Needs, Desires, Values and Yearnings Statements):

Gloria: "YesI value cleanliness very much and yet I recognize that something rather rare occurred so it's not that difficult to forgive you."

Sammy: "
Thank you, milady. I shall wash the dishes now if that's okay with you."


"Requests" (Courteous Asking
 / Demanding Statements): 

Gloria: "Thank you. I feel better. But please, let's wash together."

Sam: "
Sounds great!"

(another example of a request: "May I ride with you to the grocery store?")

Precautionarily, if you ever are involved in a conflict, speaking this way (with internationally concordant "NVC" phrasing and intent), as includes refraining from harsh insults or deragatory statements and being mindful of others' genuine needs via attentive listening ... oughta be effective.
