The idea of a period of mourning stems from a Victorian age, when everything took so much longer and they had a fascination with death. Now, to me, I prefer the more modern celebration of life. While that is undeniably occurring, the long lying in state period of mass mourning, the cessation of normal lives and a suggestion that on the actual day of the funeral, to do anything remotely enjoyable is ‘disrespectful’, is totally archaic.
You know many, many cultures do mourning. Not just Christian, post Victorians. It doesn't 'stem' from there.
I'd be interested to know which cultures don't mourn.
