You just don't know what will pop up.
I have been teaching a course this weekend (it's Easter next week in Cyprus) The Learners all come from a service background Inc Police, Army, NHS and Close Protection. The course was an education and training course. Yesterday, the learners were fairly quite. They did all the tasks I set, and did them well. Today however, saw the Learners Turn a corners and opened up on their previous lives. All bar 2 shared that they suffer from PTSD following previous occupations and the incidents they have been exposed to. This arose during my lesson on Reasonable Adjustments in a training environment. I sat back and let the Learners talk to each other (it was via zoom) about their disorders. My rationale was 'This could be a therapy session' You just don't know what will pop up when teaching and what can trigger such a turn.
