Best (neurology chief resident): The student functions at the level of an intern. He is an integral part of our team. (etc.)
Worst (psych attending): The student is unprofessional and consistently leaves after morning rounds without checking out to the residents, despite being warned to do so. He has no rapport with his patients, and is all-around unprofessional.
In my defense, the psych attending is known for totally screwing people over. I don't think he ever once watched me talk with my patients, and in fact he himself has absolutely no rapport with his patients, and is constantly belittling them behind their backs. For all the other students, he'd ask 2-3 questions when pimping them, while for me, he'd keep asking questions until I finally got one wrong, and then sit there with a smug look on his face. I seriously think he had a Napoleonic complex and was intimidated by my stature, as he is like 5'6", 140 lbs, and I'm more like 6'2", 255 lbs. From the very beginning, he looked at me with spite in his eyes.
