Well, I have run into a situation where the death and the funeral were so close together that it was impossible for us to make it. My wife's stepmother passed away in June on a Sunday night. Her step sisters wanted the funeral on Tuesday morning. They notified us right away. But they live 2,000 miles away and if we had left by car immediately upon learning of her death and drove straight through, we MIGHT have made it there a few hours before the funeral. And as you may recall, June of last year was when the airlines were a mess with flight cancellations. I could find no available seats on multiple routes to get there.
We knew from when my FIL died that her step mother and step sisters believed a funeral should be as soon as possible after death. Her dad died on a Saturday night, and we couldn't get there until Wednesday night, so the funeral couldn't be until Thursday. Her step mother took us aside after the funeral and told us she initially wished we could have been there sooner, but because they had to delay the funeral, her dad got the funeral he would have wanted. He was retired career Air Force, and if the funeral had been on Tuesday, the Air Force would have sent one person as the honor guard to give him his 21 gun salute. Because they had the extra days, they were able to assembly and transport a full 21 honor guard for that salute.
