A couple of months ago, I defended my Master's thesis and got graduated. One of the referees, a professor of mine with a history of verbal contentions between us, did me an overt injustice and despite all my efforts, attacked me with her unfair judgement. I got angry and sent her an e-mail the other day, one could say explicitly offensive and disrespectful, implying her lack of knowledge and her biased criticisms. I also commented on her wasting too much time in social networks, rather than doing academic research.
I may have gone too far obviously for I heard she burst into tears after reading the e-mail, and has notified almost all other professors about it. As a professor, do you still believe I have a chance to apologize the lady and ask for her forgiveness? If in her shoes, would you expect an apology e-mail or you'd prefer no more words from the arrogant student? If yes, what would you prefer to hear in the regret letter? And do you evaluate my reaction as provocative?
