A elementary school teacher who is supportive of her students, yet has an air of tiredness and obliviousness to her behaviour. She keeps a happy front but is deeply tired and just wants vacation to come. She is unaware of most of the happenings outside her classes.

We imagine her voice to be that of a tired woman who just wants to return home and sleep. You know when people have their index finger and thumb to show how close they are to doing something? She is that close. A voice with a hint of that would definitely be preferred.
