I would agree with you, but [parent] touched on the media, and general American public perception that people simply cannot be content in being alone. Not only that, but they also conflate introversion with preferring solitude (not always true), or even worse, social ineptitude (even rarer).

I've also noticed that some of my friends who did just like being alone ran into most of their grief trying to reconcile this, as opposed to grieving being alone.
