The Wake.

We were never lovers, and we never will be, now. I do not regret that, however. I regret the conversations we never had, the time we did not spend together. I regret that I never told him that he made me happy, when I was in his company. The world was the better for his being in it. These things alone do I now regret: things left unsaid. And he is gone, and I am old.
— The Sandman #72, part three of “The Wake”; Neil Gaiman
