I walked the woods today, strolled under the quite shade of towering old growth evergreens, their scent upon me conveyed simple peaceful solitude, there were birds and squirrels unconcerned with me, busy with their own pursuits. A young Deer browsing raised his antlered head for a quick peek, then went right back to eating. For a moment I felt as if I was the only human in the world and that thought did not disturb me in the least.
I do not know much about loneliness, I have never felt it. That makes me a rather lucky person. Perhaps even unusual.
