I love happening endings, too.
It's wonderful that you love your grandmother so much. It speaks well for her.
I'm a grandmother of three beautiful and delightful children. My greatest joy, truthfully, are those kids. My husband and I go out of our way to give those children good memories of their grandparents.
My husband was very close to his paternal grandparents, and myself, having been raised JW missed out on too much with mine. So as I've aged and been blessed, it warms my heart to read about other grandparents who are living happily, and loved by the adult children.
Again, so glad you are happy.
Cheers,
granny
