My wife had plenty of free time with my son and she gave him plenty of opportunity (by asking questions) to let her know how things are at the ranch. His main complaints are that it is too structured for him and that there is no time that he can be alone. He wants to be back in his room (and home) where he can make his own decisions and have some privacy.
Nigel, you and your wife may feel that your son had opportunity to really tell you what was going on, but that simply isn't the case. After you or your wife leaves Aspen Ranch and goes back home, your son still needs to survive, psychologically speaking, at the program. Do you think he is going to actually volunteer something that
might, however seemingly benign the context, get back to his therapist as "evidence" of his not "working his program" appropriately? Believe me, what
you might regard as raising a valid question, is
not necessarily how Aspen Ranch might see it.
Moreover, the lack of unstructured alone-time should give anyone familiar with indoctrination and brainwashing methods ample cause for pause. Doesn't this raise any red flags for you?
