OP. Yes I am the adult daughter (and one day will be the elderly mother). My parents are in their late 60s.
Op, I am 65 with a 35 yr old DD. She lives a day's travel away. I like to get a sense of her everyday life. If we're on a walk and see neighbors, being introduced. Going with her to do whatever errands need doing - seeing where she goes to the grocery store, how she spends her days. Sounds dull but it isn't. DH feels the same. With my adult son, we play pickle ball, well, sit on the couch and watch sports, boardgames, help with meals
