To be honest, most are wrapped up in their own life. They consciously and unconsciously do things. Many experiences are unique to the individual and their ability to explain it to others.
To be understood, you must have the ability to communicate your experiences to others. This gets lost in translation, because of the subjective view of the individual. Selective hearing doesn't help. If they are not focused on listening to you, then it's likely that they are not interested in you that much.
People can understand, only when they are listening. You must make sure you and them are on the same page, otherwise, lost. There are so many different factors that can be weighed upon, to add to my post, but if I continue, it would be best to put it into a hub, because one thing will lead to another one thing, then another one thing..
The best conversationalist is actually a good listener.
