Si, I was introduced to the term, 'Not my circus, not my monkeys' by a dear db friend who doesn't really post here now.
I find it really useful as I am someone who could never say, 'No'. Every time I feel like have to fix someone else's bad, or I start to feel overly apologetic, or I get worked up, overwhelmed, this becomes sort of a mantra.
As for your W, I don't know if you could be friendly/ civil without being a friend or a fixer?
You can call me Dory/ Grl.
As a wise fish once sang,"Just keep swimming!"
It's no use to go back to yesterday because I was a different person then.
