Couldn't tell you why, but I find phone calls to be strange in general. They freak me out a little. (As in, "what is with this bizarre device, and I don't like that I can't see who I'm talking to" heebie jeebies type stuff) The only person I can talk to on the phone without any anxiety or difficulty is my Husband.
I also find it extremely difficult to understand how I should respond over the phone. I've exhausted myself for a large chunk of my life learning how the average person talks, behaves, etc and what's typically considered a standard response to daily conversation so that I can pass well enough to avoid problems. It's been a long arduous process, and I'm still incapable of picking up on most subtleties, but what I've learned has made navigating the NT world much easier. So when I'm limited to only vocal tones (which.. pardon my language but there's no other way to get my point across.. I'm f****** terrible at) no facial expressions of any kind, no body language of any kind, I get all "Deer in the headlights" or I force myself to respond quickly and start rambling. I can't recall a single phone conversation where I didn't think "Oh no... did I say something wrong? Was that the wrong response? Are they angry? Annoyed? Do they think I'm weird or stupid? S*** S*** S***!"
Like many people have said as well, I don't know when I should speak so I often interrupt the person speaking or there's this giant gap of air where it takes me too long to realize they're waiting for me to talk, and that just makes it all even worse.
