I don't know why.

They don't belong to the same church, or anything.

But she "runs over," as she calls it, almost every afternoon just a little before dinner--I mean supper.
Mrs.Darling used to come then, too, when I first came; but she comes over evenings now more.

Maybe it's because she doesn't like Miss Grace Ann.

I don't think she _does_ like her, for every time she saw her, she'd say: "Oh, _you_?
So you're here!" And then she'd turn and talk to Aunt Jane and simply ignore Miss Grace Ann.
