I know it makes greathusbandbob sad but when he gets sad he says "it’s all part of this ticket called life." I like that thought. Dying and having those you love die is the price of admission.
That being said, it is such a shock to have someone there and then gone. First he was, then he wasn’t. There wasn’t even time for treatment or even hospice. Which I suppose is decidedly better than the long and drawn out (for the patient) but worse for those trying to make sense of it.
And really, there is no sense. It just is.
