You know, those kind of people frustrate me. I see them at malls, or in the arcade, usually hanging around with whichever friend can play DDR, or at conventions. Maybe I'm just getting past that target age for conventions, but it just drives me up the wall that these kids are trying to wear grown-up clothes and attempt to smother each other with attention because they are either 1) too insecure to go without physical contact for, like, and hour or 2) because they want to brag and show what they "have" off to the single populace.
So, really, to reiterate, I really have no problem with people cracking down on PDA. I only wish we could extend the reach of this rule from schools to malls, conventions, and pretty much anything else I frequent.
