We have all the legal crap finished but have not really talked about the rites.
I'm fairly easy myself. I have ideas about possible readings (Horace's odes about the fragility of life, for instance) or music for an actual service. At the same time, I would be fine with just being cremated with a reception for friends and family type of thing. I know that's what they did for my wife's thesis supervisor/research partner when she died after a lengthy illness (cancer). They did have it at the UU fellowship but there was no actual service. That eminent scholar actually gets the credit/blame for introducing us to UU'ism.
Not sure my service would fit in a house setting, tempting as it might be. Depends who came. If it was just my own extended family, sure. But even if we start including my d-i-l's family, that starts to get unwieldy (besides her parents, she has three siblings, all married, and one nephew). And if there's co-workers, friends, etc. then definitely into needing a hall or other facility.
But it certainly wouldn't have to be a formal church service of any kind unless that's what Mrs. and Little M wanted.
And if my son wanted something from his & his wife's faith (Islam) included, I'd be cool with that, too. Just don't know enough about Islamic funeral rites to know what that should be (a reading from a Muslim poet like Rumi, maybe?).
And I guess that's my bottom line. The rites are for family and friends. I get to just lay there and listen in (I'm known for being a bit lazy so that would be ultimate expression of my life, I guess).
So I'd leave a lot of leeway for my family to do what is meaningful for them.
But, yeah, something we should discuss.
