Made plans to meet a relative without reacting to their behavioral quirks.
I realize this person isn't going to change, no matter how annoyed or angry I feel about the situation. I can only change my response to them. I have choices too: I can engage with them, or I can say 'no thank you'.
But if I really want to see this person (and I do), then I have to accept their neurotic tendencies.
Serenity in action, yay.
This is a huge improvement for me. If I'd been drinking, I wouldn't have felt calm enough to tolerate this relative's quirkiness.
