A letter from Barrie to Miss Nan Herbert, Nan Ino Cooper, later 10th Baroness Lucas. From “Letters of J.M. Barrie”:
14 December 1912
My most real news is that Michael went to his school party today in ‘Etons’—first performance therin and was secretly much excited. His white shirt has filled the house (I am writing from there) since early morn, and in short nothing else is talked of in society.
