Celebrate this day, reach out or write to somebody who is starved for attention. Give them a kiss and cuddle.
As the old quote goes, old people need very little but they need that little so much.
Kannu, I have to say that I'm very proud of you for spending time with Dadu. For every sentence you write to him, he devours it 10 times, tells his friends 20 times and remembers it 50 times. When you're that old, he's 81, he can see you as his progeny. Something he has had a little hand in. His degrees. His work. His house are all immaterial. He looks at you and Diya and loves you. That's wonderful. And the golden rule applies. The fact that you are spending time with your grandfather means that you will not lack for affection when it's your turn. Keep it up son, keep huggin and kissing and loving and talking. Diya is a bit young but I can see she's also like that.
Unlike these widows who need help. Affection more like it. One day I'll take you kids to the towns next to the Ganges and we will see the real India.
