Looking back, I'd have to say I do the selective mutism thing. If I don't feel like talking, I won't. I don't always have something to say. I guess I have three things to say about this topic!
1. A few years back, I started getting into
Human Design, which is a synthesis of the Chakras, I Ching, Kabbalah Tree of Life and Astrology that provides insight into a person's unique energy (in a testable way). Whether you're into that sort of thing or not, I got a lot of insight from it. The relevant part--the Throat Chakra (or in HD, Throat Center) is where we communicate and make things manifest. You either have consistent energy in a Center or you don't.
I don't have consistent Throat energy. I generally don't have immediate responses to things. I have to wait and let things absorb and process. When I do have something to say--look out! (On two separate occasions I made people leave parties by talking about how weird Scientology is! I am no longer proud of that.)
2. I'm comfortable with silence. Some other people aren't, and I'm starting to become more aware of this. I have a small reservoir of energy I can use to simulate small talk, but it's exhausting. If someone can provide at least half the energy in the conversation--especially the topic--and do their part to keep the conversation moving, I'm fine. I'm becoming much more aware of the kinds of people I can talk with.
3. I love reading about Calvin Coolidge--nicknamed "
Silent Cal":
(from Wikipedia)
As Vice-President, Coolidge and his vivacious wife Grace were invited to quite a few parties, where the legend of "Silent Cal" was born. It is from this time that most of the jokes and anecdotes involving Coolidge originate. Although Coolidge was known to be a skilled and effective public speaker, in private he was a man of few words and was commonly referred to as "Silent Cal." An apocryphal story has it that Dorothy Parker, seated next to him at a dinner, said to him, "Mr. Coolidge, I've made a bet against a fellow who said it was impossible to get more than two words out of you." He replied, "You lose." It was also Parker who, upon learning that Coolidge had died, reportedly remarked, "How can they tell?" Coolidge often seemed uncomfortable among fashionable Washington society; when asked why he continued to attend so many of their dinner parties, he replied, "Got to eat somewhere."
