We have 10 children. Children bring us happiness. We are raising children for our own happiness. Making my children happy makes me happy in turn. That is the main reason I make my children happy.
On the other hand I would never ever expect my children to help me at my old age. When I raise children I don't think about "Oh children should help parents at their old age".
I 'll stand on the earth as long as I can by myself. And then let it go.
That is living with pride and dignity.
I have seen many old people living like that.
They are the ones who get the most love from their children as a matter of fact.
