Some of us do indeed listen, though it seems that most people are busy formulating what they wish to say instead.
That's one reason why I don't go to many parties these days, no one takes the time to listen, they're all standing there thinking what they are going to say next instead of paying attention to what the person speaking is actually saying...
*waits for you to get the last word of your question out before jumping in* that reminds me of something that happened to ME!
At least they are waiting their turn. Many don't even do that much. Listening is much harder than talking. It requires much more skill.
