Coincidence, ei?

Is there such a thing as "coincidence", or does such a phenomenon merely represent the inevitable crossing of lines? When it comes to people, i don't think that such a thing as coincidence exists. Why? Because communication is not coincidental; it's very much incidental, or calculated. People don't go out of their way to meet people just to say "hey, isn't it so bizarre that you know my sister's friends mom, who went to school with so-and-so's daughter?" Such 'coincidences' create or develop networks, which is how people interact and enlarge their circle of trust/contacts/etc. Seems logical, no? So next time you run into your ex's ex consider the possibility that it was not an accident, yet a simple inevitability.

But then again, are accidents inevitable? If perfection does not exist, then naturally screw-ups are acceptable, if not a given. I find this issue of accidents vs. incidents very intriguing...hmmm some food for thought there.
