It's almost always been a life with a few close friends, four to six.
I need mostly time alone in near-perfect silence (unless I'm intentionally watching something on Netflix or listening to music), punctuated by occasional periods of socialization with one to three friends. Even three other people is pushing it, but any more than that and it becomes a dreaded "group."
I'm retired so it's usually me and my dog and cats. When I'm out walking my dog I talk people, there are a few I see often since they are out walking their dogs too. That is about enough socializing for me. I've worked with people who couldn't bear to be alone, which would be a terrible way to be since inevitably you are going to spend time alone especially as you get older. It's something I could never empathize with; good books, a few hobbies, some snuggly critters works for me.
