Six is one of the few even numbers with good implications. There's a lot of speculation that this whole even-evil-female thing is a result of the patriarchy, but the symbology bears out so I'm not gonna bitch.

What saves six is that it's a perfect number. Being even, of course it is the number of "perfect femaleness". Six is the domesticated number; all that home-and-hearth stuff goes here. Six stands for the "perfect" mother and housewife.

Six is a very balanced number, untorn by inner conflicts and perfectly happy to stay where it's at. So naturally, "six people" are faithful, affectionate, reliable and hardworking, plus neat and loveable. *sniff* Reminds me of my mom...and on we go to seven...
