This is a question that really covers a large scope across multiple cultures and countries depending on the commenters. I don't know a whole lot of people like this because our community is so tight-knit and there's always some kind of community wide event happening every other day. The ones that tend to be take longer than the others usually are neurodivergent or introverted. Introversion doesn't really mesh well in our heavily extraverted culture, but they manage to meet someone and settle down by their early 30's or so.
