Well. It's complicated.
I teach on occassion. It's not my profession. My inclination would be never, ever to discuss my students in any way. My 'teacher' persona is unfailingly kind and supportive to and about students. I try to keep a bit of distance.
I don't think I offer, or take, that much of myself or my students. I keep it as a compartmentalised part of my life.
I have the sense that Clanchy has put far, far more time, effort and care into her teaching - for her it seems to be deeply important and meaningful. She has cared enough to write a whole book examining the dynamics of student/teacher relationships, power dynamics, subconscious subtle interplays of class, sex, culture etc. She examines her own motivations and observes those of her colleagues, students and communities.
I think she's transgressed boundaries perhaps exactly because she cares. I would say dispassionately she shouldn't be so involved. But without people who get overinvolved, maybe you get what I offer - mild, uncommitted, pleasant diversion. I doubt my classes change anyone's life. Clanchy's seem to engage and also deeply address people on a more intimate level.
I think Clanchy is too involved on a personal and a professional level. Maybe that is the lesson: Maintain strong boundaries. There may be less of a leg up, fewer teachers willing to risk their time, health, reputation to help others. Less cross pollination between different classes, races, nationalities. We will all learn to stick to our own lane, say less, keep our thoughts private, hold counsel.
Maybe we will learn that social media has reach and impact beyond what we had ever imagined; maybe we need to learn to redraw our boundaries taking that into account. Talk less, help less, fail less, offend less, interact less, apologise less, criticise less. Be kind.
So be it.
