My introvert side is really affected by phone calls. I really don’t like it most of the time. I especially don’t like how the phone intrudes when you least want it.
But I hate the phone. Hate it. Hate. It.
I can let the phone ring without picking up. I own a cell phone but don't give out the number. The only people I willingly talk with on the phone are far-flung friends, and only because I know it's necessary to keep those friendships healthy. Even so, as these friends can tell you, I can be difficult to reach, and return their phone calls in my own sweet time, when I feel up to the exertion the phone requires for me.
