I find it's getting easier in general as I get older, both functioning in general, and ESPECIALLY meeting and befriending people. The latter I attribute more to having more opportunities to meet people who share some of my interests now that I'm older, as well as living in a big place with a lot of different sorts of people, than to my own social growth. Sure, I was way more socially ret*d as a kid, but I also lived in a very small town, with a very limited group of people with whom to socialize. I think in that case, even some NTs would have difficulty making friends, if they had interests and personalities that are a bit left-of-centre.
