Huh.. I guess it's a cultural thing..

If it was ME getting an earful from that mum, I would have told her to keep her brat in check and teach him not to stick his nose where it doesn't belong.. looking at other peoples computers is rude! Then I would have told her to mind her own business. I would certainly NOT have apologized! But then again, over here people would not have reacted to that ad anyway. Nudity is mostly considered natural and not dirty.

I can only guess you are American ;)
