If I had been the 14 year old, I would have had the giggles that some man was getting his jollies from naked pinup girls. My laughter and the comments I know I would have made (nothing stopped me from saying what I wanted whenever I wanted back at that age....hmm has much changed?? ) might have clued the guy into the fact that a child was laughing at him. Who knows. Planes are public places and as such, if he wants to look at nude women's pictures, he's free to do so. Very tacky, but tacky is allowable.

I'd tell my daughter to be happy he's not an annoying person kicking the back of her chair, a person who snores for the entire flight, someone with hideous body odor, someone taking up 1/2 of her seat plus his, or a nonstop blabbermouth. There is MUCH worse than some guy who gets his thrills from nudity.
