I'm not sure if I'd call it a phobia but I definitely am at the least apprehensive about using the phone, yes. I never used to be like that. But for some reason the interaction never seems to go smoothly. Plus the fact that if I know people can overhear the phone call, it gives me added stress. I do not like nosy people, they're like spies. But in saying that, I just try to be as relaxed and as casual as I can be on the phone, like how I remember it in the 80's and 90's when talking on the telephone was the norm.
