Yep. My line manager from last year really didn't get any of it at all. We get on amicably enough on the surface but it takes a lot of professionalism on my part not to lose my temper with her about this stuff.
She is of the variety of person who assumes it's as simple as follow the plan, count carbs, inject insulin and it will all be tickety-boo, so why did I let myself/student go low and cause chaos... also she disagrees with my being totally upfront about my diabetes with my students, especially with the students with diabetes, about what I'm doing and why.
Fortunately, this year's line manager looks potentially more sensible about these things.
