Cain and Abel

本当に許すことは忘れることだ。

--ボルヘス 

“Was it you that killed me, or did I kill you?” Abel answered. “I don’t remember anymore; here we are, together, like before.”

“Now I know that you have truly forgiven me,” Cain said, “because forgetting is forgiving. I, too, will try to forget.”

"Yes," said Abel slowly. "So long as remorse lasts, guilt lasts."

--Jorge Luis Borges
