Go to church. The people there will talk to you and welcome you to join activities. During the service all you have to do is stand up, sit down, and sing along. Listening is optional. Even if you are not religious, you can treat it as some sort of research into mass psychology or systems of civilization.

To add to this: if the religiosity of modern Christian denominations is off-putting - I recommend taking a look at Unitarian Universalism. If I _had_ to pick a church to try and attend today that didn't grate with my morals, I'd probably start my search here.

Christianity has been a great brain hack for me. I recently converted after reading through a modern, literal translation of the NT (Hart). I was previously an atheist my entire life.

Distilled down, with all the noise and controversy cut out, one's left with an existential God who only asks that we submit to him, be good to everyone, and work our hardest to just be our authentic selves.

A nice side effect, as you alluded, is that one instantly gets a family of 3 billion people who are basically forced to like and accept them (as long as they're 'good' - which varies with Christian sect).
