There's nothing quite like a death in the family to disclose the hypocrites in the ranks.
It is a curious phenomenon that death can transform an odious, obnoxious, churlish, joyless, friendless, curmudgeon who never had a good word to say about anyone into a character noted for their quirky eccentricity and somewhat acerbic wit merely because they have finally, and at very long last, had the decency to pop their clogs.
I once attended the funeral of a despised personage; the 3 chief mourners, all of whom he had beaten seven kinds of shit out of at various points in his life, stood at the front of the congregation. From my rear-view vantage point, I observed their heads bowed and their shoulders shaking - whether from laughter or sorrow I wasn't able to determine.
The rest of the congregation were stony faced and remained expressionless as the coffin was eventually lowered into its 6' pit. There was no wake as such; the chief mourners departed together immediately after the interment and a group of the remaining spectators, including myself, fetched up at a local hostelry.
Even before the first pint was pulled, it emerged that the reason the service was so well attended was that many had a vested interest in ensuring that the departed was, indeed, dead and gone. Had the deceased been in a position to raise the lid of his coffin, there would have a veritable stampede to sit on it and make sure he couldn't get out before a ton of earth fell on it.
I left an hour or so after the revelries got under way and I wouldn't be surprised if they continued long after closing hours on a certain newly filled in grave.
Mourn the grandmother you didn't have, Grey, and continue to feel a healthy indifference to the one you were lumbered with. Attend the funeral service or not according to your choice, but if you do decide to put in an appearance I would suggest you take along a hammer and nails just in case reports of her death are premature.
