Every now and then, you run into people whom you thought you'd met/known before but, in fact, they are complete strangers. Yet they look kinda the same. Last night, I ran into a doppelganger of this guy I'd a major fallen out with many, many years ago. It kinda made me think, after all this time, "so what was that all about?!" The memory of what happened has all but faded but the feeling of animosity has stayed.
