Purposefully challenge - yes. Purposefully make angry - mmm not that I can think of. Purposefully rupture - no. But there may be foresight... Like, T going on a 3 week vacation, they may have the foresight to see this will cause a rupture, and begin working on ways to use that in therapy.

There is a theory about "peturbing the system", meaning kind of shaking things up to encourage people to look at change. That if a situation does lead a client to feel angry, and feel challenged about behaviors, we can get them to start looking at better avenues. But I've never looked down my client list for the day and thought "Yeup, today, I'm going to piss them off"

Yeup, we're clueless at times. Again, we're human. We miss stuff. We need our clients to go "Uh, duh, hello?! Do I need to draw you a map?" Ohhh. Click. Got it now.
