Burial, Remembrance, Honor

How do people honor and grieve their dead in your world?
There are several different ways to bury, honor, and mourn the dead. First, there are the gods way of burying and honoring a god. The way angels bury, honor, and mourn their own kind. And the way man buries, honors, and mourns their dead.

And we're doing this why? You do realize he's just going to come back. I mean, he does this every hundred years. You do know that, right? 

Gods

Now because gods do not die in a typical sense most people are not sure exactly how gods mourn for their own kind. Many will usually make up elaborate memorial services, but that's not exactly plausible. Mainly because most of the gods are busy and slightly more selfish than most humans, therefore it doesn't make sense that a god would spend several hours on a memorial service. Also, gods when gods do "die" there is a 98.9999% chance they will just come back in some shape or form. Many gods then do not see the point in mourning, burying, or honoring a "dead" god.

Remember when he first started his training and he forgot to deliver his letters? He just went to the house, knocked on the door and flew away. What was he thinking? He was so stupid when he first started.
Then he became the best of us.

Angels

However, angels bury and honor their dead much differently. First, angels do die. Secondly, angels are honored and buried in generally three types of ways. The first way is if the angel is a Messenger. If they are a Messenger, the memorial service will be much more elaborate and expensive. The Messenger will be buried, and there will usually be speeches of some sort, as well a Gift Giving Ceremony. These gifts are then burned. The gifts are a way of giving back to this Messenger, who spent all his life giving his time, energy, and patience to serving the gods. If a Messenger was particularly virtuous, a god may give a gift of some kind, which is a high honor. Generally speaking the more expensive the gifts angels or gods give The Messenger the higher honor the angels and gods give him.
If it is a regular angel there is a simple memorial service. The angel is buried as well and instead of gifts there is a different kind of giving back. Whatever the deceased angel gave to others the other angels must then give it back. For example, if the deceased angel gave her neighbor a necklace that neighbor would then return the necklace. This is how the angles honor "common" angels.
If the angel was a fallen angel or a demon these angels are not buried and are placed outside the city limits usually in a place where no one would touch or see the body. There are no gifts or speeches or any type of honor for these angels. However, there may be a small memorial service if the fallen angle was able to redeem himself in some way.
Although there are generally three ways to bury an angel they are all mourned the same way. Of course, there are variations, but most angles will spend a month to think back about the angel. Their accomplishments and gifts and blessings. Their friends and family will usually meet to talk about that person. After the month is up, the angels can mourn the angel however they want. Cry, shout, whatever they feel is necessary. But the month after the burial is a time of remembrance and mourning for the angel.

Well, if we can't bury him we need to at least close his eyes. He lived an honorable life. It's what he deserves. 

Man

The ways to bury, honor, and mourn the death of a man are not as strict as the angels. Man is either buried or burned. Even if they are burned there are almost always speeches. These speeches will usually speak good things about the person and what they did.
Even if the man who died was evil, a criminal, or a dishonorable man, there are still speeches about what that man did. Even if it is just reading off his criminal activities. The man is still a human and he deserves to be treated as such. However, there is a difference between the burial of a criminal and a generally good man. Crimainls are buried with their eyes open, while a generally good man is not.
When the eyes are opened in burial it is a way of the living humans to say, "Now you will face the consequences." If the eyes are closed that is a way to honor the good that the man did, as if saying, "Thank you for what you have done. Now, rest."
When it comes to grief this is shown in many different ways, some cry, some get mad. And none of it is seen as wrong. There is no time limit for the mourning to end. However, the tradition is that those who are mourning will wear something that symbolized their deceased loved one. Whether it's a favorite color, or their coat of arms, whatever it may be. Once they feel the mourning period is over, and they can, in a sense move on, they will then remove what they wore to remember their loved one.
Many will take it to their grave site and bury whatever they wore. This symbolizing them letting go, and this honors the deceased person.
