I often see that awful word boundaries on this forum and I just wanted to throw something out there that my t told me. My t is a smart fellow and he just said it well for me.

He calls them limits. He told me that he doesn't like to use the word boundary because it is doing something to someone else or keeping someone out.

When he talks about his limits, it is him knowing himself and what he is capable of doing. Something he does for himself to have good self care. His limits are not always set in stone either. They ebb and flow as it goes with anything. What might be a limit of his at one point in therapy is not always a limit at another time.

I like that better than always using the 'B' word.
