Blondie's story reminds me of an incident that happened at our house when we hosted book-study. We had a smallish painting (maybe 6" by 8") hanging in the bathroom which depicted two young Italian fair maidens giggling and whispering to each other as they looked at the artist, ie they looked at you. It wasn't anything you'd notice, if you casually looked at the picture; you'd just think it was a protrait.
So a little boy of about 6 went into the bath-room to do his business, but after meeting my Mom realized someone had gouged the eyes out of the girls in the painting. Of course, we asked the boy about it privately, and he admitted doing it; his Mom was soooo embarrassed. He was nonplussed, and was forced to apologize (no apparent remorse; he seemed cold).
Dunno whatever happened to the little fella, but I'm guessing he's a serial killer now....
