On pp. 400-401, there is a letter from Rand to Archibald Ogden, the editor of Rand’s novel, The Fountainhead. In the letter she informs Ogden that the movie version of The Fountainhead is going into production, and then she chastises him for not writing her a letter:
Do you remember that you promised me a letter? But I said I would forgive you anything, and I shall always be running after you, if you want me to. (I ought to say that with a smile, but I don’t know how to convey a smile on paper.) Do let me hear from you, and if you want the details about our child’s screen incarnation, I will keep you informed. It’s going to be very exciting.
(Emphasis added.) Here is one of the few instances in which any 12-year-old child (maybe 8- or 10-year-old) living today could teach Ayn Rand something: “how to convey a smile on paper” — i.e., type a smile emoticon. Judging by the letter to Ogden, it seems she might have used emoticons in some of her correspondence, had she lived long enough.
