Conversation at bedtime last night:

Me: Casper, could you [something or other, like put on your pajamas].
Casper: Yes, ma'am. [beat] I have to stop saying that.
Me: Yeah, nobody says 'Yes, ma'am" in Ohio.
Casper: And they don't say y'all! I had just gotten used to the y'all!

(Note, of course, she was born in North Carolina, but in a sliver of it that wasn't very Southern.)
