I agree that the therapist can be at fault (none of them are perfect after all). I know that I've been more at fault than my therapist has been at least once (and probably a few more times that I can't remember now)!

I also agree that the important part is in the reparation.

This one has been posted before. I think it's about a certain type of rupture. I don't think this article places blame on either the therapist or client.

I've certainly been helped by working through misunderstandings (which have felt dreadful at the time). My therapist does admit her part in mistakes that have been made (and I certainly hope it's clear to her that I'm willing to own my part in them too).
