As a cup full of sadness will not have enough space to take in happiness.

"There is nothing to forgive," Death replies. "Mourning is natural and you must deal with your loss before you can accept anything new. Keep in mind, however, that old leaves must wither and fly away from a tree's branches, leaving them bare, before new green leaves can appear."

From what i see, Death says Hello to yesterday, the past and the everything that has ended against one's wish- so that one's suffering will not last forever. Because time will past and even ghosts will be shown towards their proper resting place- and that is what will keep me alive through all this @#!@#. I figured that Death, is not necessarily must be a bad thing. It may not mean the death of a person, for it could also mean the death of an idea, feelings, relationships and what has past. In a way, it ends a person suffering. When one door closes, another door will open and through that, new beginings will be made. Change will take place.
