This is a beautiful story that tells one form, among many, of falling in love. Charlie was eight years old. At that age children usually "fall in love" with their teachers, as before, around the age of four, boys usually say they will marry their mothers and girls their fathers.
Enmma broke the scheme of life and became an advanced, exemplary figure for the children. To such an extent that Charlie calls her Mama Emma, tells her his plans and Emma responds in a guiding role. It is the role that corresponds to the teachers in the impossibility or absence of the parents.
I enjoyed your story that touches on such an important topic. Work on the clarity of your writing and keep writing, @ppvicente.
