Do you ever need background noise? I often do. My house is very quiet when I'm home alone and I find a radio or IPod playing in another room gives me just enough sense of company that I don't feel quite so alone or isolated. On the other hand, when something has really grabbed my attention, I often don't notice the quiet. I also need music not speaking. I'm an auditory learner, so if someone is talking to me, I can't keep doing whatever else I was doing (writing, reading, etc.) Even the commercials on the radio, which I am definitely NOT listening to, can interrupt my train of thought and derail it.
The exact opposite of quiet is when two people try to talk to me at the same time. That doesn't work at all for me.
What do you do to fill the empty silence? Are you comfortable in the quiet?
