One of the benefits of choosing to spend a lot of time with your extended family or your local community is that those groups will naturally have some people you get along with better than others. That’s a good thing. Being able to find common ground or polite interaction with diverse people is an incredible strength.
I love intentional communities – if you find the online fan club for your favorite book, definitely talk to them! Make friends! It’s great to do that… just not exclusively.
You need to be around people with a little more friction than that. You need to sand off your own roughest edges and find ways to interact and build together.
So go to the family reunion or the neighborhood barbecue. Not as a chore – as an adventure!
