Kevin Hearne said this quote
“ For me, the times I always regret are missed opportunities to say farewell to good people, to wish them long life and say to them in all sincerity, You build and do not destroy; you sow goodwill and reap it; smiles bloom in the wake of your passing, and I will keep your kindness in trust and share it as occasion arises, so that your life will be a quenching draught of calm in a land of drought and stress. Too often I never get to say that when it should be said. Instead, I leave them with the equivalent of a Later, dude! only to discover there would be no later for us. ”
