I guess, that when you go into this "low enegry" sphere, It isn't associated with any kind of anxiety or social fear.
Another way to describe it would be comparing it to people who are NOT morning people: the kind of person who wakes up and can't deal with anyone until their coffee has kicked in. I seem to be in that state whenever I have to deal with people
I am totally understand this view. Although I am a person with permanent high level of activities, always when I wake up, always, this early morning hours are the worst for me.
Now, usually my girlfriend or family spot, that my voice, especially responses form their questions sounds like I would be a robot. I think, this is a manifestation of my lack of any social enthusiasm.
Have you ever been compared to the robot? I guess also, that you don't like phone conversations, especially long phone conversations.
My profession, what fun, is relative strongly associated with need for the contact with people, clients. Sometimes there is hard to cover up your extremely low sociable attitude.
