Talking for the good of my health

I talk a lot (and loudly as many people point out), and I generally don't really have anything too crucial to say. But, when I'm saying it, at least give me the impression that the words are permeating your ear drum.

I work with someone (well, not for much longer, but that's beside the point) who suffers from this problem. Not only is he a terrible interrupter - you're lucky to get two words...oh, sorry, he interrupted - but he really couldn't care less what you say in between him talking.

An example:

Guy: Well...it's my last week...damn, I only work one day, I won't even be able to get my discount after then.
Me: You're an employee until Saturday, you get your discount until then.
Guy: That's really unfair, I mean, we couldn't get it at all last week, and now I won't be able to get it this week.
Me: You're not out of a job until Saturday, you have all week.
Guy: Because there's a lot of games I want to buy.
Me: You can buy them, Frank's in all week.
Guy: Damn, maybe I'll just buy them at Future Shop.

At this point I have accepted that I'm basically just there so that when he speaks, there isn't an echo. Essentially, I am a piece of foam padding. Please, don't pin anything to me, it ruins the noise absorption.

I've noticed there are quite a few of you out there (he's just the most flagrant example I have, although I'm guessing our plot-pointers probably fall into the same category). To all of you, please, please try to at least feign interest in what other people are saying. Unless you're a writhing ball of hydrogen and helium being relentlessly fused together until you burn out in 6 million years, you are not the center of the universe.
