I don't mind social calls to close friends/family, as long as I'm the one making the call. If I'm the one making the call it seems okay to me, I guess because I'm in control. I've made the decision to that I have time, and the energy to chat, and usually I have something that I want to specifically talk about. When someone calls me I go into panic mode staring at the caller id trying to decide if I'm gonna answer it or not. It feels like a surprise, and I can't decide if it's a good one, or a scary one. I like things to be planned out, and predictable. When someone calls me out of the blue it kinda throws me for a loop.
Making calls to places of business is one of my hated chores. I get out of it if at all possible. If I can't I write down everything that I'm gonna say, and practice it. Of course, that doesn't always work, and it leaves wanting to scream "no, I don't want to hear your specials! That wasn't in the script!" when ordering pizza. Of course I never scream. I let them tell me their specials only to left in a cloud of information overload, and unable to make any decision on what to order. This happens when I'm calling other places, too. If the person answering doesn't quickly get to the point of why I'm calling I seem to get confused, and unable to effectively communicate.
