I do think there's an awkwardness to British culture in this area. YYY to the poster who mentioned the euphemisms - passed away and passed - died, dead, dying are perfectly fine words yet people won't say them.
My mum (Irish) had me choose readings and hymns for her funeral and go over them with her. She's fit and healthy at 88 and a half, but she's prepared. Her will has been made for years. She has a funeral fund in the bank and recently reupped the family grave lease. I've told my DCs what they're to do with me when I die and where I'm to be buried, and I've gone over the grave business with them. My will is made.
Dad's family (his mother came from an Anglo background) were all a bit more skittish about wills. Mum packed dad off, protesting, to do his with his solicitor family member as soon as he turned 65. Dad felt a bit superstitious about it.
I wonder if the horrible delay between death and funeral observances that seems to be the norm in the UK plays a role in reducing the community spirit? In Ireland and the US (and presumably in British communities where prompt burial of the dead is done for religious reasons) a funeral and burial will take place soon after the death. This necessitates a lot of communication and notification or people might miss the opportunity to go to the wake and funeral.
In the community I live in in the US wakes are big, and people drop flowers and all sorts of essential food and home made dinners and desserts to the home for weeks afterwards.
At the wake there are baskets to drop a condolence card into, and the envelopes usually have cash inside too. Funerals can cost quite a bit, and often there's a home to be cleared and disposed of as well, and a delay until funds are released after probate.
Overall there's a practical and helpful approach, no shying away from reality.
