That's true. But for the living, being with loved ones when they die is an immeasurable blessing. I was with my mother and my MIL when they died, and I am so glad. It may or may not have helped them, but it definitely helped me. I think the inability of loved ones to be with parents/spouses/etc during these times is huge trauma and tragedy.
Can't we come up with a solution that ensures the safety of all, yet permits the intimacy at these critical times?
