Huckleberry Finn (1931)
Huckleberry Finn: [Huck is troubled, having kissed his guardian, the Widow Douglas, as he was leaving for school] Do you kiss your Aunt Polly?
Tom Sawyer: 'Course I do. Everybody kisses their Aunts, or their Mothers, or whatever it is.
Huckleberry Finn: Well, would you kiss her even if she wasn't your Aunt, or Mother, or anything?
Tom Sawyer: 'Course not. Y' don't s'pose I'd just go around kissin' anybody.
Huckleberry Finn: Well, I mean if she was, well, you know, raisin' ya.
Tom Sawyer: Oh, if she was raisin' ya.
Huckleberry Finn: Even if she wasn't no relation?
Tom Sawyer: I s'pose so, if she was raisin' ya.
Huckleberry Finn: What do people wanna be all the time kissin' you for, anyhow?
Tom Sawyer: I don't know, they just do it.
Huckleberry Finn: Women, mostly.
Tom Sawyer: Yeah. They're the ones that start it.
