" Social Activity"
The Earth is round. We live in a place that is round. Since our planet was created without any angle, it would have been equal everwhere. So nobody can find a corner, better say, and a place live out of the sight. This is a rule that we all must appear in the front of others' eyes. Isolation needs an angle and the angle needs to be out of the sight. Taking aside and living alone is unnatural phenomenon because there is not a corner on the ball which we live.
Then again, some of the most socially isolated people live in the middle of big cities, which can also be round.
Yes, they can. willy nilly, they are round
