The truth about men and dogs is that they are basically similar beasts. If they had their way they'd do nothing but eat and sleep. If you know just where to scratch, you can tame even the most savage of them. And, God bless them, if you leave your home for too long they'll tear the place apart - because they don't know where you hide all the good stuff. And deep down you both know its true.
Women are the force that led to the evolution and domestication of the wild man.
It's for the love of a woman and a family that the Neanderthal came out of the trees. If it weren't for the woman, that guy'd still be hanging out with his faithful dog, chasing rabbits and picking his teeth with the bones. But for all of the endearing qualities of Rover or Spot, or God forbid, Sylvia, the man knows that when he gets home to you, there's a lot more waiting for him than a big wet lick on the face. And Sylvia's not going to be impressed by that promotion he got or the way he helps the kids with their homework. But the Neanderthal is still kicking around in his head.
