In the 20th century you left the house because otherwise you were bored.

I love being alone but I am not "lonely" and I am never bored.

When I go for a walk on a beautiful summer night in America, always alone, there is rarely anyone outside. They are in the house, mostly alone unless they have a partner/kids.

I think we have a loneliness epidemic because we have a culture that makes it fun to be alone. Some people don't like this level of being alone but many do. Those that do aren't really going to pitch in to help so I am not sure what the solution is. You can throw a party but I am not going to show up. I would rather be alone. This is enough interaction. There is also a culture of narcissism, hyper stimulation or both involved I imagine. I can't just close the browser window in person if the conversation seems boring or jump to something more interesting instantly. I would even say that being alone is more fun now than hanging out at someone's house in the 20th century. There is just so much more to do. The group was less bored together but it was still pretty boring then. That is why going to the bar was so popular. Not much else to do then besides get drunk and smoke cigarettes in groups to get rid of the boredom.
