Now, you enjoy optimizing and racing your cars. That's fun for you! You work out the best ways to get cars, strip out the weight, get the best engine, and otherwise make the perfect car for certain racing conditions. One day, you go to a local car club. Except they are into restoring classic cars. They can speak the same lingo as you, and they can appreciate your fun, but they don't share it. You all love cars, but their fun doesn't come from getting a car to go fast, it comes from restoring old cars. There's no badwrongfun- just two different groups of people, who both love cars, focusing on different things. So long as neither group is interested in telling the other that their love of cars is wrong, there's no problem. But it is also likely that the racer won't have as much fun in the classic car club, and the classic car enthusiast won't have as much fun in a racing car club.
