"... was married to an introvert, I am now a widow. No children, no family other than the toxic in-laws long out of my/our life. I spent 40 years of my life doing well at jobs that required interaction with other employees and/or public. Enough. When I got in my car at the end of the day I felt as though a weight had been lifted off my shoulders - solitude! I LOVE the quiet of my solitary life, I grit my teeth when I have to participate in resident association meetings which are thinly disguised social gatherings - I live in a senior retirement community. I read, I stream, I read news online, I follow art classes online, I make my own art in sketchbooks, I read, I browse online, I read .... I do chat briefly, and happlily [sic], with the public library staff, the checker/bagger at the grocery store, the maintenance staff. But I love my solitary life! When I pass away perhaps no one will mourn. So what? I get tired of being advised that I'm not happy, not physically health[y], and will die sooner. Again, so what? I'm past my 'sell by' date anyway.
I'm happy with myself, by myself."
I enjoyed the sentence: "I read, I stream, I read news online, I follow art classes online, I make my own art in sketchbooks, I read, I browse online, I read."
Another writer, using the same material, might argue that one is never really alone, that you have the company of the very best of humanity when you read. You can also work with the concept that you are not not alone when you yourself are your own substantial and beloved companion. And, for some people, there is God. For others, dog.
