Perhaps the reassuring thing about grieving is that the process will not be cheated.

If we can choose where to cry, at home or with a few people who will be fully understanding, perhaps we will feel easier. But if we can't - if we are in church and a hymn catches us off guard, or at a football game and we remember being there with a son or daughter now gone - well, the earth is our home and we can cry where we want.
