The quote from George Eliot's "Middlemarch" suggests that the humor and cleverness found within family dynamics often shine best when viewed by outsiders. This implies that the nuances of familial wit may go unappreciated by those who are too close to the situation, as intimate relationships can sometimes mask the humor inherent in shared experiences.

Moreover, the statement underscores the idea that humor can serve as a social bridge, providing a welcomed relief and connection when observed from a distance. Strangers can appreciate the complexities of familial interactions without the emotional ties that can complicate such appreciation, highlighting the uniqueness of family bonds and the joy they can bring to others.
