My sister gave my two-and-a-half year old this book called 'And Tango Makes Three,' about the gay penguin couple at the Central Park Zoo. They cared for an orphan egg 'til it hatched and then raised the baby penguin as their own. I cannot get through this book without copious amounts of tears and snot running down my face.
Our parents deserve our honor and respect for giving us life itself. Beyond this they almost always made countless sacrifices as they cared for and nurtured us through our infancy and childhood, provided us with the necessities of life, and nursed us through physical illnesses and the emotional stresses of growing up.
Every animal has his or her story, his or her thoughts, daydreams, and interests. All feel joy and love, pain and fear, as we now know beyond any shadow of a doubt. All deserve that the human animal afford them the respect of being cared for with great consideration for those interests or left in peace.
