Fortunetly I was out enough with my disbelief that I didn't catch any of that shit when my dad died. There sure isn't any cure for grief. You just have to accept that really, really shitty things go hand in hand with life. And in Vonneguts words, "we are here to help each other get through this thing, whatever it is.”
At least, that's my take on it. You can always try to convince yourself that, actually, there isn't any reason for grief because Santa will soon reunite you at the North Pole, and there will be all the candy canes and toys you could ever want.
