Well...if the processing is done correctly, there should be no suffering. People tell stories about their youth because they want to pass on the knowledge and because this is part of their heritage.
Just like city folks like to talk about their lives and experiences when they were young, country folk do also. Fortunately, a lot of those country experiences revolved around processing animals for food~no neighborhood butcher shop down on the corner where we lived.
One of my favorite stories to tell is about how my grandma butchered chickens. She was one tough lady and I admired her strength and fortitude. It may sound like someone is delighting in telling of the death of an animal but it may just be that it was what we were taught to do and it wasn't a big deal. Its just one of many stories of our youth...like playing in the hay barn, milking a cow, fishing, harvesting crops.
Our nonchalant attitude stems from the fact that this was just a fact of life for us and nothing horrible, graphic or sick about it. It just was....and still is. Like going to work, making breakfast, gassing up a car, washing clothes, getting in firewood....killing animals for food was just an activity that was necessary.
