Aaauuuugggghh! I have always felt like such a dork on the phone with a T!!! But when we had our big crisis (the one that led me to PC) I called him the day of, asking him why he hadn't responded to my email (4 hrs earlier), and that was my first NORMAL phonecall with a T ever. I was mad not so much about the crisis incident itself, but that he hadn't called me to discuss it. We had an appointment scheduled the next day, but I said, did you really think it was okay to wait until tomorrow to talk about it? You were just going to come into the waiting room and make me LOOK at you?! A few sessions later, and it felt like all of a sudden we were talking the same language, when before we had been always speaking in different foreign languages. What someone posted about attunement.
So I think our anxiety or whatever on the phone is a reflection, a symptom? of the state of transference or level of trust or connection or some such psychobabble.
