Dog

We've all heard that dog is man's best friend. So much so that I'm not even going to bother putting quotes around it. It is just an accepted fact. A law of the universe. In the midst of what can fairly be described as painstaking boredom i began to wonder why people and dogs got along so famously. I say people because I've never quite been sure whether the man being referred to in the saying is a general male figure or humans as in man in general. Though I've heard that diamonds are a girls best friend. If that is true then it certainly makes a strong case for dog being a male's best friend. On a side note, it also goes a long way in describing how our world came be be dominated by the patriarchy. Diamonds versus dogs ladies? You chose the wrong side. Or did they?
Anyway, dogs. dudes. Best buds. B. F. F. If you will. Why?
The answer may surprise you as it did me. Simplicity. Yeah. That's it. That's the big secret. Dogs are simple and man is a creature who above all else values simplicity.
Another saying, "Necessity is the mother of all inventions." It could be true, it certainly stands to reason, however, consider the idea but substitute simplicity for necessity: "Simplicity is the mother of all inventions." Before you develop some wacky Oedipus complex over the wording feel free to sub in any parent or guardian figure(s) as you see fit. Language can get people all worked up. Which is a great place to start.
Did people need a language? Nah. We had grunts and we could point at what we wanted. Scream at approaching danger. Communication was simple and necessary. To simplify things even more we started to use different grunts and sounds to differentiate between things. Watch the movie, "Dances with Wolves," and try to keep up with how many times they use the same word to mean any number of things. I suspect that somebody somewhere decided he was sick and tired of being mislead into believing his dinner was meat instead of poop. The grunt sounded the same. So letters and languages developed to make life simpler. Of course it got out of hand but that's why we get forced to take foreign language classes for liberal arts degrees.
Dogs are simple. They don't need words. Just plop down beside you and slowly roll over into a position that reveals the spot they most want scratched. Hungry? Bark. Outside? Wag tail and bark. Dancing is a possibility. Simple.
