I can't think of many things more anxiety ridden than picking up the phone to make a call. The apprehensions around what am I about to say, will it come out right and what if I need to leave a message all flood my mind, causing me to stall. Suddenly the refrigerator calls to me, or the need to use the bathroom, or wondering about my email inbox.
For one, unless I've thought through my call's intention, I won't dial. As an introvert, I think through everything. Process is comfort. So ask me to do something at the spur of the moment and it happens within 10 minutes or so.
