The next day, August 21, 1842, she went to retrieve her book (though she got sidetracked). Hawthorne had already returned it to Emerson's house by then. Returning home, he came upon Fuller herself, sitting in Sleepy Hollow (not yet a cemetery). Despite Hawthorne's characteristic shyness and general avoidance of other people, he decided to join her.
They talked "about Autumn," Hawthorne recorded, "and about the pleasures of getting lost in the woods... and about other matters of high and low philosophy." Another voice interrupted them, and Emerson emerged from the trees. The conversation did not continue for too long after. "It being now nearly six o'clock, we separated," wrote Hawthorne, "Mr. Emerson and Margaret towards his house and I towards mine." Fuller's version of the day: "What a happy, happy day... all clear light. I cannot write about it."
The incident is certainly an obvious exception to Hawthorne's reclusive reputation. Fuller, renowned for her natural ability for conversation, must have been equally impressed by Hawthorne (who, you'll note, referred to her by her first name). It has been suggested that Hawthorne based the character of Hester Prynne in The Scarlet Letter at least partially on Fuller; a character in The Blithedale Romance is more obviously inspired by her. In fact, Fuller is mentioned in that 1852 novel:
"Priscilla," I inquired, "did you ever see Miss Margaret Fuller?"
"No," she answered.
"Because," said I, "you reminded me of her, just now..."
The author's wife, Sophia, was a participant in Fuller's "Conversations" (held at the bookstore owned by her sister Elizabeth Peabody; the Hawthornes were married in the same place) and was strongly impressed by her. In fact, Hawthorne got a bit jealous that his "Dove" (as he called his wife) was listening to Fuller more than himself: "Would that Miss Margaret Fuller might lose her tongue! — or my Dove her ears."
Speaking of wives, Emerson's wife Lidian grew to be concerned over how much time her husband spent with Fuller. She burst into tears at one point while hosting Fuller at the house. Fuller calmed her down by assuring her: "He has affection for me, but it is because I quicken his intellect."
