My phone Coach advises me to maintain the boundary but allow the Wait and Watch step of LRT to develop.
I'm confused by this as well, but probably because I'm not completely clear about the application of LRT. My understanding is that, being it is a "last resort," it would necessarily take the form of an ultimatum, since the next step if it doesn't work is D.
I can't find it on the thread either, so there's no context that would help put it into perspective.
