Dear Mr Prasad,
Though all of us know these proven, Guidelines , we have to ensure following , as & when we are encountered in the real Old age life, wherever you ma live?
All these , when practiced in your life when confronted, it would ensure smoother life , without causing ill will between you & the children, I would say, you must think in advance/ anticipate the likely predicament and start practicing in real life & children of this modern life would not only appreciate your decision, but also Help in their own way . such a relation if ensured, life for the entire family circle cannot be troublesome, but would be much happier.
You must ensure openness in your talks/ deeds & ensure regular conversations with one & All.
If you ensure being liberal in helping the children in case of their need even if it is not a big amount, but timely , they would rise-up when you need any help, they would willingly extending help without second thought.
It is my experience.
