In college we hit on these types of characteristics of good relational communication:
Warmth—conveying acceptance and courtesy: Warmth says, “You are important to me. You are valuable to me. I enjoy and respect you. I will not try to make you a carbon copy of myself, but rather I desire that you fully realize your own potential.”
Genuineness—having no hidden agendas: Genuineness says, “I am not trying to manipulate you, nor am I trying to bend you to my will. I want to make it safe for you to communicate with me and safe for you to trust that I will be truthful with you.”
Empathy—putting yourself in the other person’s circumstances, or walking in their shoes: Empathy says, “While I may not know exactly what you are going through, I’m trying to understand the emotions you feel and the challenges you face. I will seek to understand you, rather than trying to make you understand me.”
You can see how these characteristics will deepen one’s understand, communication and relationships.
