As I was walking across campus today, I had an interesting social revelation. I passed by a girl that I 'kind of' know, meaning, we've met a few times, said hi a few times, but whose name I cannot remember. I noticed her just before we began to pass each other and I smiled and said hey under my breath. She must be more socially mature, because she quickly responded, "Hey! What's goin' on?" To which I replied, with no thought whatsoever, "Good."
Because we were both walking in opposite directions the conversation was (luckily) over.
The awkwardness was purely a personal experience.
From the ashes of a blown-conversation came forth my most recent social revelation.
We love asking meaningless questions, and we love responding with meaningless answers, but if you happen to respond to a meaningless question with the wrong meaningless answer, then you have committed a serious social faux pas.
