Forgive and Forget?
Once upon a time in their marriage, Saul Rosenberg did something really stupid. Ethel Rosenberg chewed him out for it. He apologized, they made up.
However, from time to time, Ethel would mention what he had done.
"Honey," Saul finally said one day, "why do you keep bringing that up? I thought your policy was 'forgive and forget.'"
"It is," Ethel said. "I just don't want you to forget that I've forgiven and forgotten."
