why are you getting so damn worked up??? the greeting is not supposed to be for kids who are scared to start a conversation or anything..not even really to start a conversation. i see it as a sign of mutual respect, also as an inside joke you just want to see if other people know about. it prolly sounds really wierd to a gaper to see two random people that dont know eachother have a perfect concise little talk, thats kinda the beauty of the joke. its not meant to be an ice breaker or a way to start a friendship, its just a little inside joke. stop thinking that people are unable to just say "hey, NS" just because they want to try to use the greeting. and as for getting on the kid for not knowing NS well enough, im sure thats a joke too. i do that all the time with people, its just a freaking joke.
some people take other peoples obsession with NS way too seriously. why do you care how much time we spend on NS? you say get a life, it goes both ways on this one.
