"Death smiles at us all. All a man can do is smile back." — Marcus Aurelius (121-180 AD), roman emperor.
Stating the obvious, being death just a state, mostly caused by the weakness of the human body (a real treason against the conscience), doesn't make any kind of sense interactions with it. It doesn't have any kind of conscience. But if it were possible any meaningful interaction, except in the case of suicide, smiling to it would be like kissing Judas. It would be smiling to an odious being, that imposes it self on ourselves and on our love ones.
Laughing or mocking our tragic destiny is a much better reaction:
