Frankly, I find it a little odd how grown students are expected to call lecturers professors, but the professors — often those who encourage the honorifics — don’t use the same decorum in return. It makes me feel like they are less concerned with maintaining a respectful relationship and more interested in projecting a pompous illusion of importance. It’s a patronizing and ridiculous situation to be in as an adult, especially if you are paying top dollar. Although points taken on the email etiquette. Might as well massage their tattered egos.
