National Avenue by Booth Tarkington — Read

She was mistaken about Martha, who never had the definite hope Lena's imagination attributed to her. Martha was steadfast because she could not help it, having been born with this endowment evidently; and her tenderness for the boy she had loved so heartily was imperishable; but the Dan Oliphant of the middle years did not seem to her to be that boy. What she felt for the big middle-aged man, she felt only because he had long ago been the beloved youth; she was not in love with him, nor with anybody. This was the explanation she still found it necessary to make to his brother about once a year -- usually on New Year's Day; for it was Harlan's habit to select that hopeful anniversary as a good time to dwell a little upon his patience.

"You call it your patience, but it became only your habit long ago," she told him. "It would really unsettle you badly if I ever said I'd marry you, Harlan; and it would unsettle you even more if I not only said I would, but went ahead and did it. You'd find you'd never forgive me for upsetting your routine. If we were married, where in the world would you ever go? You haven't been anywhere for so long, except to see me, that you'd be left without the destination you've been accustomed to. It's gallant of you to still mention your willingness, every now and then, and I own up that I rather expect it and should miss it if you didn't; but if you want to marry, you ought to look about for -- well, say a pretty widow of twenty-nine, Harlan. She'd be better for you than one of the ‘buds,' though you could have whichever you chose; -- they'd jump at the chance! The trouble with me is that I'm too old -- and I'm horribly afraid I look my age."
