Bump!
Yes! YES! I often see movies alone and a couple friends have later asked me "Why didn't you say anything?! I would have gone with you!" As though going to a movie alone is a bad thing. I like going to see movies by myself because I can focus on the movie and not get distracted by the din of chatter.
Our society, on the whole, doesn't seem to make a distinction between 'alone' and 'lonely'. The word 'loner' is considered somewhat of an epithet. I think most people are incapable of being alone without feeling lonely, thus there is a stigma against being someone who not only is capable of being alone without feeling lonely but particularly against someone who
wants to be alone.
Psychologists and psychiatrists have recognized disorders like "Avoidant Personality Disorder" and "Antisocial Personality Disorder", and people at large use terms like 'hermit' and 'recluse' to describe people who prefer to be alone. There are no such diagnoses for people who are the complete opposite. They are celebrated as 'socialites' and "social butterflies".
We are conditioned to believe that being alone will make you feel lonely. Being alone is 'bad'. Being alone in thought is 'unproductive', because there's often nothing to show anyone else for all that time spent pondering.
Perhaps that's why the popularity of Facebook, Twitter and the like exploded over the past five years. Telephones are now "mobile social devices", not only capable of making a telephone call but also texting and accessing the internet through our precious "social apps".
We spend so much time on things like Facebook, and maybe even internet forums, because we believe that being 'interconnected' with people will make us 'happy' or 'better' people. But these styles of interaction are so brief and impersonal it's not fulfilling (to me). I believe it is possible to say something of great substance in 140 words or less but most people have neither the time nor the inclination to pause and think of something profound to say. They're too busy being inundated with tweets and status updates and text messages and so on.
Maybe that's why Vasilisa's thread here was quickly done and buried after a handful of responses over the course of only a week. To be able to discuss this means sitting down and reading
this,
this and
this, and then spending a lot of time digesting that information and thinking of a response more profound than "That was interesting, thanks for sharing," or "+1" (not meaning to pick on Coriolis, it was just too good an example to pass up

).
I think most people glanced over this because it's "tl;dr": a sadly ironic abbreviation.
