A group of friends go out on a trip, apparently enjoy themselves and then come back openly bitching about each other. Another group furiously defends its "group image" in front of others (Yo, we are a team, alrite!) and then indulges in brickbats and mental tortures in its own team huddle. Yet another group tries to "bond" itself with another group, failing which directs its energy in defaming the same group (reminds me the political tactics used in "First among Equals", but that's a story for another day). The remaining "free-radicals", which belong to no particular group, the left-outs, eventually form their own group out of no choice and are instantly branded opportunistic types, grouping together with sinister ulterior motives.
A human mind is the most complex machine, of course. Put a couple of them together to form a group, and you exponentially increase the complexity. Put few of these groups together and whoa, it is a mayhem. You can either go into the thick and try straighten out the inter-group issues (burning your hands in the process) or just sit back and relax, maybe grab a beer or two, microwave the popcorn and enjoy the show.
Or maybe portray an overly-intellectual image through blogs and stuff, like yours truly. Life's good.
