But why don't you think it's OK for the other poster to be a recluse? Like him, I quite enjoy solitude and that's one of the reasons I posted this. I spent a month working in a remote desert last year and found it the peace and quiet very restful, in contrast to the hustle and bustle of city life. I enjoyed the latter much more when I was younger but over time my tastes have changed.
I see no reason for you to project your standards of mental health onto other people, even if you don't share their inclinations.
