I totally have as many boundaries with my students as therapists do with clients. Possibly more. I freely admit they're mostly there for me and my sanity, though it's barf-tastic how many colleagues of mine pretend they're there for the student: "It will enable you to learn best if you call me Professor Jones while I call you by your first name."

Perhaps we're defining boundaries differently, but I don't think therapists are unusual in the number of boundaries they set. Prison guards. Parole officers. Doctors. All of these professions set what I would call boundaries.

I do wish therapists would quit the malarkey about in whose interest the boundaries are, though.
