Several years ago I was in one of those dreaded corporate meetings. One of the managers running the meeting compared the problem we were discussing to "herding kittens". I just LOVED that image.
I have been owned by cats since I was five years old. You do not control them. They control you. I know that it is impossible to "herd kittens". However, I like to be in control of things. (Why on earth would you live with cats? You may ask). So, perhaps if we spell it a bit differently, it will have a different meaning and effect. Besides, I have never been the best speller. So, "hearding kittens" is kind of a metaphor for a lot of things. Mostly its about the chaos of life.
