I do want some airtime when I speak

Why is it that I so rarely get to finish telling a story, or speaking about what's going on with me? I always make an effort to listen to others when they're telling me what's going on in their lives, what their worries are, what their joys are... why do I seem to have an inability to elicit that from those to whom I've turned in the past? It's become almost endemic amongst a certain subset of friends.

Maybe I just think I'm speaking and am not actually being heard?
