A member of CaSfA recently posted this link on her Facebook page: http://www.latimes.com/news/opinion/commentary/la-oe-0407-silk-ring-theory-20130407,0,2074046.story. The article is very interesting and fits with our recent topic of what to say and not say to a cancer survivor.
You start by drawing a circle. In it, put whom ever is at the center of a trauma such as cancer. Then draw a circle around that. In it, put the person/persons closest to the person in the center (such as a spouse or children).
