The Challenge of Making Friends as an Adult
You don't even need to me approaching middle age. I'm in my 20s and moved halfway across the country recently, and am continually amazed at how hard it is to make good friends of the same gender. Given all the websites/events/groups dedicated to meeting people to date I've found it far easier than ever to get dates, but more difficult to make friends. It's a weird reversal. There's probably an opportunity for a little business there, but I haven't quite worked out how it would work.
