I'll tell you who it isn't - the neurosurgeon. Once while I was doing my psych rotation (I was on the C/L service), I had pulled up a chair next to a patient to interview him (this was a competency case b/c pt was refusing brain biopsy for tumor). Now I am a white female, 24 y-o at that time, and the patient was a black male in his late 30s. The neurosurgeon happened to walk into teh room in the middle of my interview with the patient. As soon as he saw me he got all excited and asked me "So you're the patient's mother?" I just sat their waiting him to laugh because I thought it was a joke, but he was looking at me with anticipation and I realized he was serious, so I just replied "No," and he was like "Damn!" I would have thought that if our appearances weren't enough for him to figure this out, at least my short white coat with the school badge would have given it away.
