Currently When the Time Comes: Families with Aging Parents Share Their Struggles and Solutions By Paula Span see related

Yesterday in the car:

Lyla: I told Dad that when mom and dad get too old for me to take care that I
will move in with you and Daniel.
Clayre: When will that be?
Lyla: Probably when I'm 12.  Then when you and Daniel get too old for me to
take care of I will move in with Amy and when she's too old I will move in with
Joel and when he gets too old I will probably be old enough to get an apartment
and live on my own.
Clayre: How old will you be when that happens?
Lyla: Probably your age.

Oh man.
