With my favorite shows on summer hiatus, I’ve found myself reverting back to a few of my trusty standbys. Recently, I’ve had the pleasure of re-watching the comic genius and relationship hijinks of Seinfeld. Sure, I know all of the lines and can anticipate all of the plot twists, but there’s something pleasingly familiar about my sitcom pals from the good ol’ days. While happily meandering through memory lane, it occurred to me that it has been over twenty-five years since Seinfeld first aired. To highlight the show’s continued relevance, I thought I might remind you of (if you are my age) or introduce you to (if you are younger) some of my favorite relationship “facts” that have stood the test of time. In this article, I will draw from the “The Invitations” episode from 1996 to highlight the role of similarity in attraction.
