Only my opinion follows:
I look at the fact none of us can control the lives of others, no matter how much some may want (or wish) to. I choose to be thankful for any time I can interact with any of my family members in any manner.
Some of our grandchildren (I'll never be lucky enough to witness any great-grandchildren) don't write thank you notes, but I don't hold it against them or their parents. Holding a grudge against them for some perceived slight can grow in us, build walls, and compound ill will and hurt.
Life is different now. The demands, pressures, interests, and more on younger members of society are far different than when I was young. Growing up my grandparents lived on our street. Now our children and grandchildren live many states away.
I'm thankful I can focus on what I do have rather than what I think I deserve.
Strength, Courage, & Peace
Thank you, Scott! I needed that!
