When I've been around people like that, I usually start backing away and share less and less because I get tired of it. I know that's not really constructive though. It doesn't assist either of us. Luckily this doesn't happen too often. I wonder what happens when I get in that mood? I think people just kind of let me go on and on while they move on to other things and just drop it. I try to keep an eye out so I don't behave that way though.
