"I'm gоin' tо tаlk reаl plаin tо you: I never have sence I married you, but I'm goin' to now. I 'ain't never complained, an' I ain't goin' to complain now, but I'm goin' to talk plain. You see this room here, father; you look at it well. You see there ain't no carpet on the floor, an' you see the paper is all dirty, an' droppin' off the walls. We 'ain't had no new paper on it for ten year, an' then I put it on myself, an' it didn't cost but nine-pence a roll. You see this room, father; it's all the one I've had to work in an' eat in an' sit in sence we was married. There ain't another woman in the whole town whose husband 'ain't got half the means you have but what's got better. It's all the room Nanny's got to have her company in; an' there ain't one of her mates but what's got better, an' their fathers not so able as hers is. It's all the room she'll have to be married in.
