My parents never really made a big deal about it. They didnt get all into the psychology of explaining it. Myself and my 3 sisters just went along with it. I think its easier for farm raised children to grasp alot of things and not make a big deal out of it, we saw the bull breed the cows, the goats fight, the cat kill a pigeon, etc. When we would get pigs, my dad would playfully suggest food names like porkchop, but he always told us why we were getting anything new, if it was for breeding, he said so, if it was for eating, again he told us. Once my sister, the most soft hearted of us, asked if she could have a pig that we wouldnt kill after it got big, knowing how much time she spent with the hogs, and that she fed, watered, and tamed them, making it easier to handle them, my dad got her a lil pot bellied piglet, and he lived with a lone duckling for many years as a pet. There are many facts of life that having animals gives a parent an opportunity to teach. I remeber the first time i felt rejection, it wasnt from another kid at school, it was from my grandpa's work dog "buck". He wasnt mean, he just didnt like to be petted and wouldnt come to the house, he stayed with the cows at the barn or in the pasture, and only had eyes for my grandpa. My pa told me that was his place in the world, his job, and his happiness, and that was okay to let him be and do what made him feel good. He contributed in a positive way and that was all that mattered, my pa then told me that my uncle was arnery too, but we all put up with him because he would stay up all night watching the hog roast!!!!
