Hearing is not agreeing

In recent days I have come across people who have said they or others they know are in situations in which they were not heard or were not listened to. Someone postulated to me that perhaps it wasn't that they were not listened to or not heard but merely that whom they were speaking with did not agree. How many times has this happened to me? It is possible that many times in the past when I thought someone was not listening to what I had to say, simply did not agree with me. Hearing is not agreeing. Someone can listen to me and hear what I have to say without agreeing. I must strive in the future to make sure that I know where someone is not hearing me or just disagreeing with me. Each one has different conotations and require different responses in turn.
