Some years after I finished my PhD, I was offered a position in the Comp Lit program at UCI (probably part time, but I'm not sure). Apparently, some visiting experts on Russian lit and Nabokov had admired parts of my dissertation. But I turned it down, feeling unprepared to teach Russian literature to graduate students. After all, I was never able to get the background I needed to do that. Undergraduates I could have managed; however, grad students at UCI--that would be another story.
It is true that I have had one personal responsibility after another--my son, my parents, as well as my own anxiety to grapple with-- but it felt as if I were fleeing this opportunity out of fear.
Perhaps after my experience at the University, it was best to stay away from the place as far as such a job is concerned, but perhaps not.
