MRS HALE: (looking about) It never seemed a very cheerful place. COUNTY ATTORNEY: No — it's not cheerful. I shouldn't say she had the homemaking instinct.

MRS HALE: Well, I don't know as Wright had, either.

COUNTY ATTORNEY: You mean that they didn't get on very well?

MRS HALE: No, I don't mean anything. But I don’t think a place'd be any cheerfuller for John Wright's being in it.
