In order to influence a child, one must be careful not to be that child's parent or grandparent.
Behind the line
What it means
Our interpretation.
The saying jokes that parents and grandparents are disqualified from influencing a child. Its advice is impossible to follow once the relationship exists, which sharpens the irony. The implied complaint is that family closeness can make persuasion harder, despite the authority that relationship might seem to promise.
