One of the most fundamental accommodations is preferential seating, so I understand the student's frustration. It sounds like the student wasn't complaining as much, but more advocating for her (?) needs, as well as yours. It sounds like she was wondering why you didn't tell the teacher you needed to be up front.
You were a junior in college though, so maybe you felt that the seating arrangement was okay. Did you feel it was a good place to be? Could you easily reference the terp and the teacher at the same time?
