I've actually seen something like the begining of the video on the road, and in malls.
I shit you not, 2 blindingly idiotic looking females were chatting loudly on their phones... but something was odd, they were looking at eachother and laughing, and then when I could make out 2 sentences as I walked by, it seemed like they were in Conversation with EACH OTHER.
Needless to say Face palming ensued.
