I'm sorry this had to happen. I, like you, have great responses that come fully formulated in the car on the way home. I believe what MrChicagoRN posted was spot on. Practice saying it in the mirror, to friends, and family. Just like an actor runs lines. Because this is how these situations usually come...when you are unexpecting and unprepared with an audience no less. I asked a great veteran nurse early on if that had ever happened or what she would say if it did. She replied, "I tell them my husband and my father don't talk to me like that and I am certainly not going to be spoken to like that by you. Now you can call back, or we can go into this empty room when you calm down and are ready to try this again." If you can imagine it delivered in an extremely proud voice by dignified lady that was 6'2".:)Never had to use it. However, the day isn't over yet.
