No-one is finally dead until the ripples they cause in the world die away, until the clock wound up winds down, until the wine they made has finished its ferment, until the crop they planted is harvested. The span of someone’s life is only the core of their actual existence.

-Sir Terry Pratchett, Reaper Man

As long as you remember him, you carry a small spark of his existence with you. And with every story you tell, his ripples will continue to spread.
