The Left Side of the Couch

My dog loves to sit or sleep in the left side of the couch in my house’s living room. No matter how I hush him, or try to make him move, he just sits there. It reminds me of Sheldon Cooper in The Big Bang Theory, who also adore the left side of his couch to the maximum. My dog doesn’t put a reasonable argument for him sitting there, but Sheldon does have a long and pretty scientific reason for that. But I believe they do it for the same basic reason: comfort.
