When I come across people like your 'orrible DN I think to myself I have no Mum, no Dad and no spouse therefore there is no one who can chastise me. I am an adult so if someone thinks they can make me feel uncomfortable by looking down their nose at my efforts they get short shrift and a mental backhander.
These kinds of people have what I call 'Shiny Button Syndrome' meaning that their uniform/the fact that they sit behind a desk or counter/have their ID hanging on a lanyard has given them license to say or do anything they fancy and woe betide the client/patient who has the temerity to question their position.
So if your review is with the horrible DN you must impress on her that you know what you are doing, meet her on her own territory with eye to eye contact and body language that tells her 'I am in charge here, you are here to advise and support and no more'.
Sock it to her, girl!
