“I saw it. I saw the little house.” (Or possibly “I seen it…” etc.)
I’m thinking southern writer. Eudora Welty? I also considered Katherine Mansfield, but I don’t think so. I just can’t remember.
The gist of the story was that a rich child got a dollhouse as a present, and the poor child was invited to see it, but wasn’t considered worthy. Or something like that. Race may have been an issue.
