Kudos indeed. I'm glad Tptacek brought up the often-neglected 'flag' feature.

Again, there's no accounting for taste, but offhand I'd say labeling curse words, and their creative use, as "childish" is quite overreaching. Have you read any David Mamet, Frank McCourt, or Larry McMurtry lately? Do you honestly feel a child would have sufficient skill to structure prose in that fashion?
