I occasionally adjunct. What students call me at the beginning of the semester is always awkward:
Them: "Hello Professor"
Me: "Technically I'm not a professor."
Them: "Okay, we'll just call you Doctor."
Me: "Yeah, about that... not a doctor either."
Them: "So why are we paying you?"
Me: "Technically, you're paying the school. And the school is paying me... very little"
Them: "Answer the question"
Me: "Because I know stuff that you don't."
Mostly they still just call me professor and I feel awkward every time.
