Let me try and make this simple for you. Let me explain this with a small example.
—" There was a bull standing in a field and there were a few flies which decided that the bull had enroached into their territory. They decided to stand up to the bull. The bull without even realising that these flies were trying to stand up swayed its tail and all these flies just ran for cover. "
Hope you understand. Sometimes it is good to know what these flies are.
