I have a very pre-DTMFA approach to friends and family. I can't think of anyone whom I have affirmatively cut out of my life. I enjoy people who, like me, cling tight to their bullshit like a dog mangling the leg of a mail carrier. One of my friends is obsessed with soccer performance metrics and modeling team cohesion stuff, and I love hearing him out. Another is a theologian who is now a crazy person living in a cabin in the woods, and he will teach me fabulous things about Gnosticism on a seemingly unbreakable monologue until I tap out. These are not easy friends to have or keep, but I do it because it's so worthwhile. But it's hard to sustain that commitment for someone whose overriding favorite topic is themselves.
