The oldest doctor here is a 70-something English professor who is always dressed resplendantly with a new tie or bowtie for every day of the week. In his downtime he either paints scenes from the hospital, or sits on his porch reading the paper and smoking his pipe. He doesn't ever get flustered, he is a wealth of knowledge on Africal diseases, and he is very encouraging to the students.
His favourite praise is "well done" as in, "You did a lumbar puncture - well done" or "you got a chest X-ray on that patient - well done". It's nice to get praise, until you realise just how easily he dishes out the compliments, "you've been here for two days already - well done" or "you arrived on Wednesday? Well done".
Um ... thanks!
