My maternal grandmother's eldest child died from leukemia, around his 7th birthday. I know what that does to a family, for generations.
And yes, people go through death, mourning, and grieving in different ways; however, Cindy's words and actions are now so far away from actual grief, that you must discount "grieving"! What mother, who is GRIEVING, goes on to support the very people who actually killed her son ? Cindy has. Think about that.
I give up. What part of I-find-her-behavior-disgusting-too don't you understand?...and, yes, I see how stupid she is being. Geeze.
