An excerpt of a letter from BR to Mannin, on his attraction to her, found in Mannin's Young in the Twenties, page 62.

BR had told Mannin that talking with her was more exciting than making love with almost anyone else. The "almost" was inserted because BR did not want a lady in America to be offended by the statement, as "her talk also is exciting, less so than yours, but it would be rude to say so in print."

BR said that what she had written had been "quite a considerable event" to him. The only other time he had "such strong delight from praise" was when Einstein wrote a preface to a German translation of one of his books. BR said, "For I do not think you are much in love with me."
