You will not see: take your aging, demented parent to work day. Or: Aging, Demented Parent Room at the gym, so you can exercise while someone else watches your parent. Or: Company/University Picnic or Christmas Party with !Special Activities! for aging, demented parents. Or: Aging, Demented Parent Care at your professional meeting, so if you have to bring your aging demented parent with you, you can attend some sessions.
Aging, demented parents have many of the same social and psychological issues as young children. Toilet issues. Inability to deal with hunger issues. Lack of executive function, self-control, and easy frustration. But aging, whether demented or not, parents are seldom as endearing as small children. Other people's demented parents are orders of magnitude less charming than other people's children. We live in a society that often warehouses our elderly. The quality of that warehouse is directly proportional to resources. At the bottom, they are called "Medicaid Mills" and meet "legal standards", but are horrific in any societal sense. They may be better than living by oneself, eating cat food, with no cleaning, personal or household, available. They may be better than taken into the woods, or out on the mountain, and left to die in the elements.
Some mornings I wake up missing my parents, who my mother used to be. Other mornings I wake up either furious or despairing of the burden I have in caring for her. And my burden is not particularly heavy, compared to others. I want to meet the children of my trainees and my colleagues. I rejoice in their families. But I do not kid myself: no one wants to meet my very sad, aging, demented mother.
