I have two adult children (41, 43) the same thing has occurred with them even though I speak with them via text, email, FaceTime or in person (when they are in town) on a weekly basis. Seems to me that unless we tell them our expectations they don’t know or care, somewhat selfish on their part. Now I’m doing my own thing, or at least trying . Which means I tend to worry less, out of sight out of mind and don’t attempt to fix things for them. I certainly have cut back on the giving of things without a mutual respect of “thank you.” I have ended phone conversations that turn into “I know” on their part. Different times, I would not say it’s the best of time. Technology, jobs, friends, careers take time away from family togetherness. Sad.
