she insists on calling a practice nurse 'sister'. As in 'Sister Jones'.
'Sister' to me conjures up an image of Sister Julienne in call the midwife- or any nun for that matter.
My mum is elderly and seems to put anyone medical a) on a pedestal and b) as if 'sister' implies this practice nurse has huge seniority.
On the practice website the nurses are not given any titles just their full name- eg Sue Jones, Anne Brown.
I am a bit worried my mum is making a bit of a fool of herself by calling the more senior one 'sister' all the time when she requests an appt.
I have tried to tell her that a title like sister would only apply in a hospital setting - if at all- but she won't have any of it.
