The Desert Mermaid

Back when I worked in a public library, we'd have preteens taking the "Joy of Sex"-type books and either ashamedly stuffing them between the reading cubby shelf and the wall, or else cramming them among the Garfield books. I never understood why they were bold enough to go to that stretch of shelf to grab the book in the first place, but never bold enough to go put it back in that general area (not that they would have reshelved it correctly, but at least it wouldn't have been where some poor little fan of the Sunday comics might find it).
