For the past two or three years now, I have taken long walks through the forest just behind my house, mostly when I'm bored and there's nothing to do (it can get rather lonely living in a small house far away from any town or city). I never had any real problems with these walks; nothing that would ever cause me to feel nervous or uncomfortable. This all changed during the winter of 2010. I continued walking, hoping that something would rid me of this feeling. Even something like a caw of a crow, even though it is not a pleasant sound, would at least let me know that I wasn't alone.
