Listen to understand them and their words, rather than just for your turn. Good listening means being willing to turn off the TV, close a door, or stop reading your mail. Give the speaker your full attention, and let them know they are getting your full attention. Empathize with the other person. Especially if they are telling you something personal or painful, or something you intensely disagree with, take a moment to stand in their shoes, to look at the situation from their point of view.
Some people take longer to find the right word, to make a point or clarify an issue.
Give the speaker time to get it all out before you jump in with your reply. Watch your own emotions. If what they are saying creates an emotional response in you, be extra careful to listen carefully, with attention to the intent and full meaning of their words. When we are angry, frightened or upset, we often miss critical parts of what is being said to us. Be very slow to disagree, criticize or argue.
