One of the most annoying listening behaviors is interrupting. People interrupt because they listen to respond. They're simply rehearsing their answers and waiting until they have their say. Frequently, they interrupt because they're really more concerned with being understood than being understanding. This is not listening. True listening is suspending the ego and focusing on the other person. As St. Francis of Assisi said, "Grant that I may not seek to be understood, but to understand."
