Teacher
How you relate to an authority figure; feelings developed in school and still active; something you are learning or want to learn. An important lesson you are meeting in life and need to learn. If it is a teacher you know, then it would depict what you feel about that teacher, what feelings they provoke.
Something to learn or teach. Sometimes this is higher learning in which you learn about life or your life. But frequently it is about things you experienced and therefore learned from teachers at school or college.
If you are the teacher it can show your relationship with other people in terms of what you have to offer them in terms of your life experience or knowledge.
