I'm not a big fan of phones. In fact, it would be safe to say, I have a phobia when it comes to phones.
At work, I can have a message on my phone that takes forever for me to check. I love my parents, but loathe having to make a phone call. In fact, I've tried to get my dear mother to use email to no avail.
If it comes down to talking to someone on the phone or by email, I would chose email all the time.
It's a wonder that I was a customer phone representative for four years. I wasn't a good one, but I was one.
For persons with Aspergers, dealing with what might seem to be a regular social interaction can seem like trying to climb Mount Everest. I know that it's quite common for aspies to have a fear of phones for the same reason some aspies hate being in crowds or going to parties: it means social interaction, something we are not good at.
Of course, I can't use autism as an excuse. Most people use the phone for communication and I have to learn to control my fear. For me, it might mean writing down what I want to say and even learning to only be on the phone for short bursts of time. But since I can't control the world, I have to learn to live with it as it is.
Just another one of my quirks...
