Am I spending too much time alone? In effect, I think I am. My effective social circle has shrunk, for various reasons.
There are a few difficulties in making new friends, or just talking to people. New England has a kind of reserve to begin with, that doesn't encourage talking to strangers. Smartphones and other devices have added fuel to the fire, or whatever the opposite of fire is. On the street or in any public place, the majority of people by themselves just aren't there, and you aren't there for them. A charming extrovert might be able to get through, but that's not exactly me.
Since this is partly a technological problem, I'm applying some sort of technological solutions. Today I emailed an old friend who's been out of state for a few years, and with whom I'd fallen out of touch. Now we're back in touch, which is nice. And in terms of seeing people face to face, I'm in the process of joining more Meetup groups. I'd already been in a writing group. Knock on wood being in touch with more people will help with that too.
