I think it comes from the heart....do you think our bodies want to be hurt? They heal (as best as they can), when they break or cut....so what makes us think the foot or injured flare is something it wants to do?. Our bodies are reacting.... So being kind and saying it out loud may sound funny, but it is consoling.
Remember when little and a high fever any kind word gave us a comfortable feeling.
So to everyones monster....hush tonight.... Give us back for a few moments what used to be ours.
