I'm in the process of writing a funeral service that I'll be taking in a couple of weeks and I just checked my notes; I use the words 'died' and 'death' except for when I describe sitting with the person as she 'left this life behind'.
I don't care what words people say, but I do wish we talked more about death and, in a sense, prepared for it better. (No, nothing can really prepare for the death of a loved one in emotional terms, but practically we can address certain aspects.) I've never been to one, but I do approve of the concept of 'Death Cafés' - although I suspect they appeal to people who already have an open approach to the subject. The whole subject can be fraught with difficulties that could be made easier if only people talked about it more.
