Try to kill a fly; you have to find them and trap them in a bottle or cup.
Lies, make up less than a fraction of 1 percent of a narrative of truth.
We read these narratives as if they were One big truth without remembering the lie. However the lie has done its damage to someone; and it waits hiding to hurt someone again. All seems positive when it is thoroughly evil and aimed at someone in the bright light who is obviously good person. Flies and lies are evil and unwanted in our lives. They have their own leader: Lord of the Flies. See the Movie "Lord of the Flies"
