Aristotle (; Greek: Ἀριστοτέλης Aristotélēs, pronounced [aristotélɛːs]; 384–322 BC) was an ancient Greek philosopher and scientist born in the city of Stagira, Chalkidiki, in the north of Classical Greece. Along with Plato, Aristotle is considered the "Father of Western Philosophy", which inherited almost its entire lexicon from his teachings, including problems and methods of inquiry, so influencing almost all forms of knowledge.

I don't know what it is about death that makes it so hard. I suppose it's the one-sided communication; the fact that we never get to ask our loved one if she suffered, if she is happy wherever she is now…if she is somewhere. It's the question mark that comes with death that we can't face, not the period.
