The Living Boundary

When you say no to someone, when you say it's a living boundary, you're essentially saying this is a place that we can't cross because of X, Y, and Z. Like I cannot go meet a friend of mine for dinner every night, Thursday night because he's going through a rough time. I just can't do that because I've got family things that take priority over that. And that's where the living boundary thing comes in, I think, because you have a core value or belief as we're using the term here.
