When you were 30, she called with some advice on the baby.
You thanked her by telling her, “Things are different now.”
When you were 40, she called to remind you of a relative's birthday.
You thanked her by saying you were “really busy right now.”
When you were 50, she fell ill and needed you to take care of her.
You thanked her by reading about the burden parents become to their children.
And then one day she quietly died.
And everything you never did came crashing down like thunder.
“Rock me baby, rock me all night long.”
“The hand who rocks the cradle...may rock the world”.
