With just myself in mind, I don't really like the idea of a funeral or burial. Seems like a huge waste of money to me. If you're spiritual then you believe that I've simply left my body behind as I've no more use for it. It's just an empty shell I used to inhabit, nothing more. If you're not spiritual then I'd be even more surprised that you'd be interested in a religious service such as burial. In either case it just seems like a waste, I'd rather be remembered as I was when alive, not laying in some box waiting to be lowered into the ground as a bacteria buffet... Although in thinking about it more I guess that the funeral isn't for my sake at all; it's for the closure of the people I leave behind when I die rather than myself, so I'd let someone know I preferred cremation and leave the final decision up to them.
As far as my own loved ones I'm of the same opinion as stated earlier; funerals and burials are wastes of money. I'd rather celebrate the lives of the people I cherish where they lived, not go to some cemetery and reflect upon the fact that they're not around anymore.
Sorry about your dog.
Jam it back in, in the dark.
