One of the side effects of growing old or being disabled is the feeling that the walls are closing in, like the walls of those rooms of the Inquisition that actually closed in, pressing their occupants to death.
My personal walls have (figuratively) closed in until I now have a living space of 3 by 4 feet, in which I spend most of my time. My recliner is now "my place in the world."
Such a restricted life would be intolerable if I did not have letters, newspapers, books, magazines and TV to expand my mental horizons. I have always loved solitude; I dread to think how the isolation would affect me if I were the "party girl" type.
No matter what our circumstances, happiness and contentment come from within. One can feel devastatingly alone in a crowd of thousands. One can have all of the comforts and luxuries life has to offer, yet be bitterly unhappy and seething with discontenment.
