Weird things you tend to do in your game more often than you want to admit

I don't know it it is weird, but a repeating pattern in my games is my sims forming factions and acting out rivalries with other factions. Often I set it up like that in the beginning, but even if I don't, it usually ends up this way. Also regardless of what social class my sims start in, sooner or later they all end up in positions of power (what in turn can lift their rivalries to some pretty dangerous level). I think the reason for this is that I'm more interested in advancing my worlds' overall story than in the individual households.
