Hell, I'm like that today!
I have those days when I don't feel like talking about anything to anyone, as well. Hell, people in general upset me anyway, and I can only take so much bullshit in a week before I need to cool my jets and clear my mind of the stupid shit I hear about.
But, I also have a pet peeve about talking on the telephone -be it one of those days, or when I do feel like talking to people. I just don't like talking on the phone. If you call me, get to the point and hang the fuck up!
I have a best friend (who I haven't heard from since August of '07, AND that lurks here from time to time

) that would call and we'd talk for about 10-15 minutes about current events and tech talk.
Our rule of "phone conversations" was: "If there's more than 10 seconds of dead silence or rambling, it's time to hang up, dawg." Also, if one clicks over to answer the other line and they aren't back in 30 seconds, hang up.
(Damn, I didn't feel like calling dude, but now...

)
Although I don't particularly like talking on the phone, I will kind of force myself to stay on for a while, especially if I'm bored or don't have anything else better to do. It's like "I could sit here in an empty house listening to/reading the news by my damn self, or I can at least humor someone with conversation
But you DEFINITELY aren't alone on this one.
