I know many people who hace find partners like this. Including me. If it wasn't true, most people would be single, since no one fits a moldes completely and most people won't even fit it partially. For example: only a small percentage of people are high earners. Most people are acerage height and have average bodies. All that average people get married. Your coworkers go on dates, have relationships and some of them are married. I could go on, bug examples of perfectly normal average people finding someone are around you. They are not the perception. Even the "nerds" tend to find someone with similar interests.
