Oh dear. I think a lot of it was pressure that they were being filmed, or they wanted to impress all of their friends or something. Either way, it doesn't say anything good about American teens. Stupidity or insecurity, take your pick.
I am concerned about our future as a country. I think I might just flee to Japan.
The only problem with that is that Japanese young peoples' ignorance about the world and other such issues is comparable to Americans'. Having been an exchange student, I've learned just how sheltered Japanese teens (and people in general, really) are. Ultimate example: my host sister wasn't sure that London was in England. >___<;;;
