On the way home from day camp:

MissSix: (spying '60s-era decrepit motorhome in a parking lot) Aw, look at that! I want that! I want to live in that! That would be cool!

Mr11: Yeah, it's like you could live anywhere you wanted and sleep anywhere you wanted!

MissSix: Hey, when we grow up let's live in that! It can be our clubhouse!

Mr11: Well, most grown-ups don't live with their sisters. They live with their wifes or all alone.

MissSix: Ohhh. (thinks) I could live in the attic!

Mr11: There aren't attics in motorhomes.

MissSix: There aren't wifes in motorhomes either.
