Annie has become 'more' than just a person who instructs her. Annie has become a friend, mentor, and in many instances a surrogate mother figure. As far as Helen's definition, one has to state that in some cases some teachers are exactly this. However, in today's society it is more difficult (and even legally dangerous) to become involved in a student's life outside of the classroom. More is the pity, of course. In the end, it is the student that loses (and quite possibly society as a whole). This does example the lifetime impact that a teacher has on a student.
