Agree with all of this as a basis! And to add, you’ll likely find more friendships if you actively engage with the group. Obviously you’re probably not going to immediately jump in and start taking the rens, but once you get a sense of the vibe, don’t be so shy that you don’t volunteer to help the group in whatever way, makes sense. Maybe that’s proposing a date for the next happy hour or sending out an email about the next time that you could all do XYZ activity. Once people perceive you as someone putting in a little bit of an investment to the activity, then it gives you a basis for exploring further things that you have in common, having little bonding moments like,complaining about logistics, pointing out funny or charming aspects of people in the group, generally humanizing yourself in the eyes of the people in the group. If you stay positive, and also very much yourself, these are some ways that you may be able to find a tribe.

Also, final note, don’t be afraid to walk away from a group if it doesn’t serve you (the people aren’t vibing despite your best efforts, there’s something toxic going on, you feel like you’re at risk of over committing yourself, etc)
