Now that I have graduated, I have come to realize that I carry a deep grudge towards two of my professors. Not being able to process the negative feelings, I sent an angry e-mail to one of them a couple of days ago. I didn't hold anything back, because she had always been an arrogant ******* who had never paid any attention when I tried to tell her something. I was astonished when she replied (instead of just ignoring me) and she actually seemed sorry for the way that I felt and for the fact that I wasn't able see anything positive in the years that we spent together. Now I'm thinking that I should write something nice to her and try to reconcile, but I don't know what to say. Nevertheless, I am considering sending another angry e-mail to the other professor too, who was the ultimate ******* and quite the bully towards clueless freshmen such as me three years ago.
