It's good to hear one person's own feelings about bereavement.

Of course, th1s is such a personal event that another person will probably have a totally different take on it. One size does not fit all and, IMHO, one needs to be aware of the person to whom this is happening and to deduce what their own individual needs are, rather than going in taking over without permission. To some that would be like taking control away from them at a time when they most need to have that control.

I would also be very careful about bringing God into the conversation. For a lot on non Christians this might not be welcome. Keep your religious platitudes to yourself unless you are sure that they will be welcomed.
