With Sterling Cooper for sale, Betty finding Dick in a box, and JFK's assassination and feminism's second wave on the horizon, people's worlds are going to change, and they will each see it differently…"but they don't really want to."
Last night's episode was titled,"The Color Blue," referencing this post-coital conversation between Don and Sally's teacher Suzanne,, wherein they ponder a question one of her students asked, "How do I know if what I see as blue is the same as it is to you?" Don remarked, "People may see things differently, but they don't really want to."
Part of the shared human experience is the desire to be understood, to have others (or at least someone) see things as we do. But another part of the human experience is that we each have a different lens—shaped by our individual experiences—that renders a worldview unique to each person. So, basically, we're all doomed to misunderstandings.
Exhibit A: The teacher's brother.
He has epilepsy (or "fits") which is making socialization/work/life difficult for him: it freaks out those who don't understand the disorder. As the brother, Charlie, sees it, "Other people are the problem." He's tired of being misunderstood to the point that he doesn't want to even try to assimilate anymore. His sister tries to renew his faith in humanity when she tells him, "People are ignorant. They're scared of things they don't understand." But he may not have understood.
Exhibit B: Paul Kinsey
He's in the "other people are the problem" camp as well. And when he says "people" he means women, specifically Peggy. As Peggy pointed out to Don when she was asking him for a raise a few episodes back, Kinsey makes more money doing the same job as he does ("and not always as well"). In this clip, Paul's pitch for the Aqua Net account falls flat, but Peggy comes to the rescue with some good ideas. Paul sees her good work as a negative reflection on himself, rather than a positive reflection on his team.
Paul thinks he's telling Peggy something she doesn't already know when he says, "Wearing a dress isn't going to help you with [the] Western Union [account]." Clearly he thinks being a woman is a benefit for Peggy's career, rather than a hurdle.
While Kinsey was jerking off and getting wasted, Peggy was actually hammering out ideas, and making sure to keep track of them. If Peggy views her gender to be a hurdle in this business, maybe she understands that she can't do anything to fuck it up.
