Read this passage from Mark Twain’s Autobiography. What is Twain’s main point about his mother? She had a slender, small body, but a large heart--a heart so large that everybody's grief and everybody's joys found welcome in it, and hospitable accommodation. The greatest difference which I find between her and the rest of the people whom I have known, is this, and it is a remarkable one: those others felt a strong interest in a few things, whereas to the very day of her death she felt a strong interest in the whole world and everything and everybody in it. In all her life she never knew such a thing as a half-hearted interest in affairs and people, or an interest which drew a line and left out certain affairs and was indifferent to certain people. The invalid who takes a strenuous and indestructible interest in everything and everybody but himself, and to whom a dull moment is an unknown thing and an impossibility, is a formidable adversary for disease and a hard invalid to vanquish. I am certain that it was this feature of my mother's makeup that carried her so far toward ninety.
She was interested in everything and everybody.
She had a slender, small body.
She lived to a very old age.
She was an invalid.
