I enjoy every word you type... especially because of your style and ability to create such vivid imagery. The word "gaol" helps create the tone.. it is the perfect word for the piece, no other word would have relayed the the feel of what you are saying.
The topic is definitely one to get the brain working, I am appreciative of that! I spent a good deal of time thinking about the condition of the animals we keep and I've often wondered if it was "right" in the order of things. In the case of horses, their domestication was pivotal in the advance of our species, but the human condition has changed to the point where horses are simply kept for pleasure for the most part, no longer a necessity for our survival. We use animals for our amusement and entertainment much like the Romans did at the Colosseum (maybe not quite as brutally but you get my point), so morally speaking, is it right to cage them and keep them? If it's not right than what's to be done about it?
I own a parrot. I whole heartedly believe that birds should not be kept in cages, I find it rather cruel. My parrot was born and raised in captivity and if I were to set her free she would surely die. Which is morally correct? Keeping her safe in her cage or allowing her to fly free the way nature intended only to meet a most definite demise? In a perfect world, there never would have been a parrot for me to purchase as they have no business being pets, but that isn't the world we live in.
The topic is dark and very deep, and I think for most people who have empathy it is understood perfectly. In my perfect world there would be no caged or kept animals, but unfortunately that isn't the world I was born into. All we can do is make life a little better for the animals that we have been put in charge of.
