Imagine a world where the tendency to be social is viewed with suspicion.
In such a world, kids shun their talkative peers. Those who frequently gather in large groups are looked upon as strange. Children are discouraged from feeling drawn towards crowds and parties. Feeling overly social is discouraged in general. Adults, on the other hand, are encouraged to work alone rather than in teams. The loud and gregarious ones are chided.
In such a world, the entertainment industry is less glamorous, though still highly appreciated. Literature and science are far more advanced, and these things are more glamorous; the lone researchers and novelists are especially admired.
In such a world, being reserved is the norm, and it's a trait that's prized and nurtured. The leaders in society are the ones who are seen the least. They strive to say what they mean, and they tend to do so with few words. They're thoughtful and effective. They don't lead for the attention, but because there's value in it.
In such a world, the tendency to be social is pitied. Many people try to change you if you happen to be that way. If it weren't for the fact that science had advanced so far, being so social might even be considered a disease.
Imagine a world where those who tend to be "too social" are made to feel uncomfortable because of it. Perhaps in that world we can find understanding.
