How much do you listen? feel heard?

I’m mean both on and off Fluther.
I see : sometimes towards me, although that’s usually because I didn’t explain well : more often I’ll just be watching a dialogue, maybe a verging argument, and someone will come back triumphant at another with a point the other had already fully expressed. And the ‘already-been-there’ would be clear if the first had just been listening?
Then I wonder, how much we actually hear each other, or if we just go off in our bubbles of reality, bumping into but never merging with others… and then I start to wonder how much I’ve done that.
When I, I feel like I listen, or I feel like I try to listen. But when I see this phemonenon, I wonder how much I succeed…
So how much do you think you succeed, you hear? And/or how much do you feel heard?
Let’s merge our realities for a bit if we don’t already?
