Death.

An unlikely person dies without just cause. There is a book to sign your name in - to commemorate it... How strange.

Life is so beautiful, I would be angry at death if it came to take me too soon.

One side celebrates the life, while the other side is proper in mourning. They do not understand each other. One is proper, formal, procession - like these peoples and their signing of a book. The other has a fest with food and laughter, along with the sharing of good times and memories - to honor the person in death.

Others consider a certain age the celebration and donn everything red.

It is inevitable. It will happen to us all. Nothing to fear, nothing to set aside a set belief for. Just a part of the big life picture and another journey. Perhaps, another life.
