Just Feels Wrong

My grandfather was 84-years-old when he passed away. His birthday way in October and he was gone by January. I still don't understand how it happened so fast. Today I was listening to the radio and heard the radio personalities talking about Hugh Hefner's birthday (of all things right??) and tomorrow he will be 85. How is it that Hugh Hefner, a nasty old perv, has gotten to live longer than my amazing grandpa? It may be selfish but it just feels wrong to me and hurts more today than it has in a while, even if I can't quite put my finger on why.
