How cliché, "opposites attract." What do they do after they've attracted each other?
All the time at work, at O'HARE AIRPORT (so I have a pretty good sampling), miserable couples meander by. The women who just walked out of Better Homes knowingly empty their minds over celeb rags, the burly macho men soak up business books...and then pay for their wives' magazines. Sometimes, men will enjoy conversations with me about westerns, history and/or sci-fi - masculine genres. Their wives/girlfriends envy me for not only getting along with their men, but also for having the knowledge they don't*.
Aside from their decisions to fit traditional roles, these men and these women are utter opposites. They aren't genuinely attracted to each other because they actively hide who they are!! And they don't get along precisely because they're opposites, they don't relate to each other. The same fights over and over again: "don't go back to the bathroom, you'll spend another 20 minutes on your hair;" "you never hear anything I say, you're only interested in your fantasy football." Opposite interests, repulsion rather than attraction. These couples rarely share similar projects...they're each other's projects!!
Speaking for myself, I'm generally attracted to people to whom I can relate. I'm androgynous/masculine, and I'm attracted to people who have similar qualities (high femmes can have very big balls/ovaries). As a feminist, a sci-fi nerd, an artist with high appreciation for science, a cuddler, etc. I'm attracted to people who share these qualities.
It makes more sense to me to tackle projects with someone similar than to tackle someone who's my opposite. And much more arousing.
* it is possible, yes, that these women just genuinely aren't interested in those genres. I've been told or overheard too many women say "I wish I could enjoy math/science/sci-fi/history/technology/etc. more, but it scares boys away."
