There is a particular kind of professional relationship that has no clear analogue elsewhere in teaching. Not quite mentor and student. Not quite collaborator. Not quite editor, though there is a lot of editing. Not quite therapist, though there are moments, usually around the sixth month, always on a deadline, where the line becomes difficult to locate. Supervising a Master's thesis is its own thing entirely. And a year of it, which is what the Digital Design MA requires, is long enough to watch someone change.
