Over 35 years ago a workmate of mine a bloke asked me why I was off the day before and I told him I went to a funeral of a relative.
As we talked he said his brother had died when they were both in their early 30's and then blurted out "I did not go to his funeral." (They both lived locally to the other) I asked him why not. He said, "he was dead he (his brother) would not of known.."
The guy was not joking and it has stuck in my mind since - the bloke was a good workmate we had laughs/chats but that made me feel uneasy and funny about him
