Understanding the mechanics of planetary movements is nothing special. People are astonished at the differentiation between celestial bodies. I think the immensity of these objects overwhelms people must like many men are overwhelmed at the sight of a woman. Each planet has a surface, or face, and we observe the differences between each planet as if they were a woman (in a hetero male context). People are naive, and pets are coping mechanisms. Otherwise, individuals cannot live in certain environments without an animal to ease the mood. There are idiots living in inhospitable 'homes' with roommates that they shouldn't be around. Unfortunately, life isn't fair.
