It actually bothers me how many people "prefer to be left alone"
And then we wonder why such high levels of depression and social anxiety in our society. I'll be hard pressed to be convinced otherwise.
Valid point, though I'm happy as a clam being just alone by myself, and usually more stressed around people (generally large groups). I know lots of people who are the exact opposite too, so I don't think you can make a judgement solely on that.
