This is a great perspective, thank you 🙏
There are a couple people I'm friends with, who I was referring to in the OP, that I've known were pretty incompatible with me for a long, long time, more than a decade. But only recently have we become closer just out of convenience if a mutual friend. But that base incompatibility is making itself known again, and it's time to set convenience side and make the mature decision to scale back and be closer to acquaintances rather than close, personal friends.
