Barbara did not love her--how could she?
Moreover, there were other physical things: the lean, shining marble of Miss Letts's long fingers, the dry thinness of her hair, the way that the tip of her nose would be suddenly red, and then, like a blown-out candle, dull white again.

Fingers and noses are not the only agents in the human affections, but they have most certainly something to do with them.

Moreover, Miss Letts was too busily engaged with the survey of her relations, with now this gentleman, now that, to pay much attention to Barbara.

She dismissed her as "a queer little thing." There were in Miss Letts's world "queer things" and "things not queer." The division was patent to anybody.
Barbara's father and mother were also surveyed.

Here Barbara was baffled by the determination on the part of both of them that she should talk, should think, should dream about all the things concerning which she could not talk, think nor dream.
