It Occurred, ink, 2015
"It occurred to him that what had appeared perfectly impossible before, namely that he had not spent his life as he should have done, might after all be true.

"But if that is so," he said to himself, "and I am leaving this life with the consciousness that I have lost all that was given me and it is impossible to rectify it -- what then?"
-Leo Tolstoy, The Death of Ivan Ilych
