basically act like God does not exist and approach is humanisticly.
The Reverend knows there are no answers for something like this in God.

prayer, etc., it is not the time for others to bring in god.

There is not rational explanation here with or without invoking a god.

... parents who lost a child at Sandy Hook. You can just be there and help in any way you can. But I doubt that there is any comfort you can offer.

I like the last thing she says the best:

"I can't imagine what you are going through, but I am here to support you in whatever way feels best."

Precisely. Just be there and go through it with them.

Sometimes people just don't know what to say and say the wrong thing.

I've gotten more than once of those stupid sayings in response to my cancer, and I find it even more unbelievable someone would say shit like that to someone who lost a child.

Sometimes it's better to not say anything. Sometimes its better to just be. Buy the person a meal. Wash their dishes while they mourn. Throw out their garbage. Hug them if they want it. Mourn with them.

best thing could do.

I remember all the losses during the worst of the AIDS epidemics. Every memorial and funeral just go quieter. There was just nothing more to be said.
