I can't tell whether this particular person is real, but I fully believe that there are thousands such people, if not more, in every developed country. I count myself among them. My social media interaction, other than Lemmy and Reddit, is limited to reading and writing 1000+ words long blog posts. I recently left our company's Christmas party after an hour when I realised I had nothing to talk about with the others - I don't know the current trends in movies, TV or music, and nobody in my work shares my interests. So, I may be perceived as just as weird (or endearing, as the ending suggests), even though I see myself as perfectly normal.
