Hearing is easy, it comes naturally to most. Listening is work and most are lazy. If some truly listen, hear what you are saying and it confuses them or is perhaps a serious subject, they find it easier to relate if it is somehow connected to something they have seen, heard before, or experienced. So it does become a "all about me" because it was identified and processed that way. It was easier to figure it out because in some past way I related to what you said. And I can respond to you by quoting my experience- or my life -or my -or my---- or my. And then I don't have to be worried about how it affects you and deal with your problem, I can just tell you how smart I was to solve mine. Very easy
And then there are the good ones; -- they lear your words, read your face, listen to your emotions and wait until you are done before they jump into the conversation with something that might truly be helpful.
