I was staying with friends when I heard about this tragedy, and I immediately got a splitting migrane.   

I couldn't imagine the intensity of grief the parents and family were enduring. 

At at time like this you would want to crawl into a hole and drown in your depression...

So the Jewish culture over centuries has developed an antidote - about as good as it can be - sitting Shiva.

The mourners are visted by their friends and neighbors - hundreds and hundreds of them.  Visitors don't need to knock...you just walk right in.   Bring a plate of food to share. Talk about the living and talk about the dying, recollect your memories.

Difficult to do - take GRIEF head on and overwhelm it!
