Yes, figuring out how to be, where the lines are...
My biggest challenge is to remain open and hopeful (but not with the hopeful puppy face, as T^2 says), without expectations. I'm much better at closing out the potential pain. That line is hard to find -- the balance where we take good care of ourselves, protect ourselves, while still remaining open to R.
Pia Mellody's boundary lessons definitely help with that. If I'm doing well with my own internal boundaries, then other people's storms don't rock my boat. Still, it's a constant challenge and a constant learning experience.
