In Laurie Notaro's book "I Love Everybody," the author humorously highlights the consequences of mixing different backgrounds or personalities, particularly when a person with a problematic past, or a "black sheep," has children. The metaphor of the black sheep suggests that such individuals might not provide the best environment for raising a younger generation.

Notaro uses the term "supervised visitation" to illustrate the challenges that arise when a reckless or troubled individual becomes a parent. This phrase evokes the image of needing guidance and oversight, further emphasizing the responsibility that comes with parenting and the potential complications when not approached thoughtfully.
