Unfortunately, I'm not finding a way to meet other Catholics. My autism (high functioning) definitely inhibits my social skills, but there just aren't any events to interact with others. My church doesn't even do coffee and donuts after Mass because they need everyone to leave ASAP so the parking spots can be available for people coming to the next Mass.
It's a similar situation where I'm at, though we still manage coffee & donuts somehow. After the last mass some people hang around for a good hour.
We need to find a solution. Whoever lives closest should make a habit of inviting people to hang out there, by announcement from the pulpit. I'm about to write to a priest I know to see what he thinks. We had a priest who would try to organize an occasional group outing or Catholic game night, though I think he didn't come anywhere near using the fullness of his persuasive skills. There were a few such events, but a decade ago.
