Everyone has heard of the "Love Triangle," but did you know love comes in all other sorts of shapes and sizes?
You and someone else both like the same person. But it's not an equal amount, as you like them WAY more, and show it by sending them gifts and standing outside their window with a boombox over your head.
You're in a long distance relationship in which your significant other moved across the country or you're both going to college. They say distance makes the heart grow fonder, but they left out the second part where the genitals grow colder. Your significant other meets someone in their new proximity and begins to cheat on you until they finally have the heart to tell you they think now is the time for each of you to explore new things (read: other genitals).
This happens on purpose on TV shows like Wife Swap and by accident in movies like Closer. You and another couple trade partners in what you think might be a clean switcheroo that was most likely brought up by alcohol and a well-timed proposition in a "joking" manner.
You catch eyes with someone in a bar or on a subway, and feel a connection and fall in love...but you never actually meet. You think about them from time to time (mostly while masturbating), but all you know of them is the imagined life you'd live with them. If you live in a city with public transportation, this happens about 37 times a week.
You like her, but she likes him and he likes this other guy AND that guy likes this other girl. It's an endless cycle of people liking people...who like other people. Some people call this "life" and you should be ready to deal with it.
You can't even find one person you have feelings for, and when you finally do, you mess it up by going too fast too early and drunkenly blurting out "I love you" on the third date or texting them 19 times in a row. You're bound to spend the rest of your life alone, with your only real companionship coming from cats or a sex doll...or some weird combination of both.
You're in an orgy.
