I am an Anesthetist and this one MD started in on (during a case I might add) , "You know when Obama was little he told everyone he was from Africa". I said (tired of this crap, and frankly surprised hearing it from an educated person), "You know, I don't believe all of that". His face went red and he starting spewing " You know he was editor of the Harvard Medical Review and it said he was the first African American from Africa to be the editor" I said " Medical?". He got snarky and said in the tone of a ten year old "No LAW, he's a LAW-yer". I said "Well, you said Medical". He harrumphed , and said a few other things..but it was dead in the water.
There were a few other sentences I can't remember well..but I just remember sticking to "I don't believe that he is Kenyan". What is weird is that we usually got along well and we still had to do 2 cases together. So I just acted my normal cheerful self..and truthfully, he kinda acted chagrined. But I just looked him in the eye and was pleasant. What is weird is that I have noticed that since then, I see him looking at me from the corner of my eye. Maybe he is overcome by my beauty and charm (HaHa) or maybe he wonders why someone who would NEVER agree with his politics is accepting and positive toward him...ah the mystery.
