I have had a couple of family members since 2020 who died in their 90s.
Both (one in her own home, one in a care home) loved to welcome younger members of their family who visited, loved to hear what we had been up to, and shared family reminisces (especially welcome when they told embarassing stories about our parents as children 😂)
If they had then heard we were coming with a string of complaints about our parent/sibling, and expect them to DO SOMETHING, I suspect that they would have found a medical appointment to put us off!
