I have no idea why people choose to teach the kind of material that’s related to their deepest traumas. She is sadistically setting students up for a failure while masochistically torturing herself.
I’d never teach works of literature that mention late-term fetal loss, stillbirth, or gestational diabetes because I know I can’t be unemotional about it. Students should not be subjected to projections if they unwittingly touch a sore place in a teacher’s psyche.
