I actually opted out so the chaplain couldn't find me and somehow they still ended up dropping by during my recovery. Luckily this chaplain was pretty chill, it could have been a lot worse - but it was still a stressful event for me and against my explicit wishes and choices.
I wonder - what do you think the purpose of a chaplain is - all of this has made me think more about chaplains and their role. I tend to be cynical and think the worst, that being that chaplains are basically there to try to convert people when they are vulnerable (after a surgery can be a traumatic time, and a significant number of religious conversions occur after a trauma). There is also the opportunity to convert before death, so that might be playing a role too. But I need to actually read up on the history and context, maybe my cynicism is misplaced here.
