When I was a graduate student, I was a teaching assistant (more than once) for a very inspiring mentor, a man named Manos Vakalo. His teams of teaching assistants had remarkable autonomy. He never questioned a grade we gave, and he always treated us as respected equals. In retrospect, we could be dumb at times; I remember bringing beer to a critique for our undergraduates, and Manos simply raising an eyebrow in reprimand. That, however, was enough. He had remarkable expressions, every one of which I think I could still imitate perfectly today, nearly 20 years later.
