What role should a parent play in the months of preparation that lead up to a coming of age celebration for a child?

I first started taking this question seriously after I stood on the Bimah, uttered the traditional parental blessing that freed me from “personal liability” (shepetarani mei’onsho shel zeh) for my newly dubbed “teenager” and tried my best to connect to the blessing on an emotional level. It was not easy. As much as I felt a release in that moment; the parental part of me was actually sensing a growing set of legal and moral responsibilities that I would carry for the actions of the pimpled, brace-faced teen who stood before me in his new suit and tie.
