The Look of Disbelief from your Senior Resident
You are still learning. or you think you know things like you know everything already. 2nd years get cockier. and senior in their 3rd or 4th year, last year of training may be the wisest and cockiest. You may still make mistakes. Premature closure on the differential diagnosis or premature disposition? Wise fool you seen when you utter unwise things. You should learn that look early on in your career. Better than being yelled at or scolded on, or embarrassed on rounds in front of year peers.
