Years ago, when writing our joint will, DH and I stipulated that we both wish a full Requiem Mass and burial in a Catholic cemetary. That if one of us dies when on holiday, the burial is to take place there.
In any event, as little money as possible is to be spent on coffin etc.
For years, I sang professionally amongst other things at weddings and funerals, so to me it only made sense to write our wishes down, especially after being the person doing most of the arrangements for my parents' funerals.
Now that DH as been diagnosed with cancer, obviously the thought intrudes again - far less academically now, but as far as I know he has not changed his views. Hopefully, there will still be a few good years left to us together, but to any who hesitate to discuss the subject: it is easier to talk about whilst you are fit and well, rather than once you know death is approaching rather faster than you would like.
