Case. A stepmother tries to become a “real parent” to a teenager, meets resistance and “you’re not my mother”.
Model. Trying to grant yourself root when trust hasn’t grown yet. A parent’s rights can’t be seized by decree.
Protocol. Start as a kind, reliable adult; discipline stays with the birth parent; trust is granted gradually.
Lesson. The role grows from trust, not from a status on paper.
