Agreed. Rather too much "Diana hysteria" creeping into the show of condolences I feel.
I, too, have lost Christian, Jewish and Muslim mates and I'm certain that all of them would rather be remembered at a bacon butty and beer bash rather than receiving insincere, or inappropriate, references to God.
When my wife died (unexpectedly young) some of the most moving tributes came from my Muslim friends who attended the church service in her memory.
I was a Christian, and although confused by the fact that God "moves in a mysterious way" remain one!
I still believe that much of the public showing of grief, particularly to someone they did not know, is so much over the top that it becomes cheap and tacky.
