As a child I observed children banging their head on the floor in an attempt to force the capitulation of their parent to their childish whim. It worked for some of the kids and most who engaged in this act are trying it out on wardens across the nation. (As a rule wardens do not respond to this as hoped).
Not as often I have witnessed grown men and women bang their head on the floor or against a wall. I have never done this. Ok, I have beaten someone else's head against a floor or wall.
An angry man states:
"He was so angry that it's like he was stung by his own poison."
"Stung by his own poison" is a picturesque way of putting "Banging your head against the wall."
On Monday I was the guest speaker at Dine With A Doc a meeting of senior citizens in Greencastle, IN. It was a great time. During the question and answer time one of the folk wanted know if forgiving and forgetting was impossible. I answered; No, it isn't, but you have to really want to, you have to be more concerned about your health in all three areas than getting even. Not to forgive is as damaging to you as though you were literally stung by your own poison.
Acts 8:23 "For I perceive that thou art in the gall of bitterness, and in the bond of iniquity."
