Late at night, when I should be asleep, I read Ask Reddit, where a horde of anonymous strangers gather to ask and answer questions big and small. Browse Ask Reddit for long and patterns will emerge. Queries are unwittingly recycled, and the more universal the question, the more often it appears. One question (and its variants) is raised with troubling frequency: How do you make friends as an adult, and why is it so difficult? Responses can number in the thousands, but they always hit on the same themes: It is hard to make adult friends because, perhaps excepting work, you have no natural place to meet them.
