@Hellometime ”Giving 20 days notice and an emergency life or death situation do seem incompatible though.”
I disagree. My dad had a serious cancer - it wasn’t clear how long he’d live. He had a good relationship with my nephew and really wanted his grandsons (who lived overseas) to see him before he deteriorated and became a shell of himself due to the the side effects of medication, arduous medical treatment, and the encroachment of his brain disease (which high caused amongst other things the loss of speech in his last four months).
It would have been awful if my nephews - who only saw grandad infrequently - had that memory of him.
So we arranged for the kids to visit in a break from treatment - my dad had a few good days with them, quietly at his home. They never had to see him at his worst. I will never forget driving my brother and his boys back to the airport and my dad standing on his doorstep waving goodbye to them. We all knew the boys would never see him again, it was such a sad and precious moment.
Sometimes the aim is to see someone BEFORE you are at death’s door, and planning it for a time when everyone can enjoy that time has immense value.
