Summarize this article in one sentence.
While you don't need to become proficient in Klingon, you should make an attempt to understand your partner's obsessions. Follow some of the movies, books, and games that your partner loves. Who knows--maybe they'll become your obsessions, too.  A relationship is a two-way street. You should show some interest in your partner's passions, and demand that your partner do the same for you. Don't worry if you don't understand some of your partner's passions. While some shared interests are important, you don't need to share all of them. Your partner's nerdy obsessions and social awkwardness make them who they are. You shouldn't try to change them, and moreover, you won't be able to. If you can't accept them, then you probably shouldn't be together. Don't tease your partner for their mysterious obsessions. They've likely had to put up with such teasing their entire life, and more of it will only cause them to withdraw. Nerds often thrive on routine. They are very sensitive to change, whether it be at work, on the road, or at home. Simply moving an item in your partner's room might upset them. You partner may have a designated space in the home where they like to work or pursue their hobbies undisturbed. They value the predictability and security of this space, so be certain not to violate any boundaries. Ask before cleaning their space or moving any of their things. If you are the type of person that craves spontaneity, dating a routine-oriented nerd might seem challenging. However, you can still do spontaneous things with your partner, like traveling, by combining more spontaneous activities with more structured activities. For example, if you want to go on vacation with your partner, have a balance of very structured, highly scheduled days, and days that are more laid back. This might sound counterintuitive. Shouldn't the nerd be explaining to you? The truth is, you'll probably know more about many subjects than your partner. Nerds tend to specialize in one area of knowledge, which means you'll probably know more than they do about more mainstream things, like cars, pro football, and non-science-fiction movies. Don't belittle your partner for not knowing much about mainstream topics. Instead, try patiently explaining. Your partner's friends are important to them. You should take an interest in them, despite the fact that they'll probably be pretty nerdy, too. That's not to say you need to spend every night LARPing together. Rather, make sure you hang out with them sometimes, ask them questions, and are generally friendly. You may not like all of your partner's friends, but you should accept them. Try to understand and appreciate what they bring to your partner's life.
Take an interest in your partner's passions. Don't try to “cure” them. Respect your partner's routine. Find a balance between spontaneity and routine. Be prepared to explain mainstream pursuits. Take an interest in their friends.
