Wanted to add: As a teacher, I know that when I can predict a change coming, I give my kids forewarning and preparation. It isn't always possible; some changes are unpredictable and we just have to deal with those as they come, but preparation is key in making those changes go smoothly. When at all possible, therapists should be doing the same, and it is very clear that in some cases, therapists are not adequately preparing clients for anticipated change.
