For most people, incest is just a weird, wrong, and unspeakable act. Just the thought of any sexual attraction or physicality with members of our own family brings immediate disgust. Yet this is in our society and culture. In the novel, Lefty and Desdemona seem to have a different situation. Even though I could never ever picture myself with my sister, or cousins, or any member of my family, if you try hard to put yourself in their situation, you can sort of see why they did it. I feel like they didn’t want or choose to fall in love with each other, but their minds naturally adapted to their situation. There aren’t any available women in their small town, they are best friends and all that each other has. That plus the hard times they are in with the war just seemed to force them together. It also says in the novel that in their town it was acceptable to marry third cousins, which technically they also are. This is why i think their minds just naturally adapted to their situation and just forced out the thought of them being brother and sister. Around other people, they were brother and sister, ut together they were cousins. Eventually as their charade kept going on longer and longer in Detroit, they just accepted and forgot that they were related.
We cannot fully understand this situation because we hopefully will never have to experience it. But i do think we experience this kind of love all the time, just not with our brother or sister. Think of most romantic comedies, songs, or shows. Taylor Swift’s “You Belong With Me” is about two best friends who realize they have loved each other the whole time. Countless movies occur around this theme too, with a few coming to mind are ones like Thirteen Going on Thirty, The Ugly Truth, and Maid Of Honor. All these movies centralize around really close couples falling in love. So besides the fact that Lefty and Desdemona are brother and sister, their situation is not uncommon, and we would not question it at all. We would probably just try to make it a movie.
