Srila Prabhupada Says:

You are thinking, "Now I have arranged everything. Things are going very nicely. Now I'm very happy." But, all of a sudden, the death comes. That you cannot avoid. All of a sudden. That is... Death is described in the Bhagavad-gita. What is that death? That death is Krishna.. That is stated in the Srimad-Bhagavad-gita: mrtyu sarva-haras ca aham. That means death will come, your all asset, your so-called children, your family, your bank balance, your friends, your country, your leadership, your pride and everything will be taken.

>>> Ref. VedaBase => Srimad-Bhagavatam 6.1.24 -- Honolulu, May 24, 1976

Although they forget death, death will not forget them. Suddenly they will be kicked off the platform of a peaceful family life. One may forget that he has to die, but death never forgets. Death comes always at the right time.
