TO MRS. WILLIAM THAW 12 Newbury Street, Boston, December 19th, 1898. ...I realize now what a selfish, greedy girl I was to ask that my cup of happiness should be filled to overflowing, without stopping to think how many other people's cups were quite empty. I feel heartily ashamed of my thoughtlessness. One of the childish illusions, which it has been hardest for me to get rid of, is that we have only to make our wishes known in order to have them granted. But I am slowly learning that there is not happiness enough in the world for everyone to have all that he wants; and it grieves me to think that I should have forgotten, even for a moment, that I already have more than my share, and that like poor little Oliver Twist I should have asked for "more."... TO MRS. LAURENCE HUTTON 12 Newberry Street, Boston. December 22, [1898] ...I suppose Mr. Keith writes you the work-a-day news. If so, you know that I have finished all the geometry, and nearly all the Algebra required for the Harvard examinations, and after Christmas I shall begin a very careful review of both subjects. You will be glad to hear that I enjoy Mathematics now. Why, I can do long, complicated quadratic equations in my head quite easily, and it is great fun! I think Mr. Keith is a wonderful teacher, and I feel very grateful to him for having made me see the beauty of Mathematics. Next to my own dear teacher, he has done more than any one else to enrich and broaden my mind.
