Sometimes, I get tired of talking.
You see, my job entails me talking with people on a daily basis. I talk when I am conducting training. I talk when I am in meetings. I talk as I run into people in the office. I talk to vendors and clients. Occasionally, I get weary of hearing my own voice.
When I get into these moods, I like to keep quiet in my off-time. I try to work on tasks that I can do on my own, like cleaning up filing or washing the car or painting my model soldiers -- tasks that I can do without speaking to anyone.
I doubt I could ever become a hermit -- I like people far too much to isolate myself forever -- but I have to admit that I cherish my periods of silence.
