In the excerpt from Jodi Picoult's "House Rules," the author highlights the pressure on mothers to present an image of perfection. They are often seen as "supermoms," expected to handle every challenge with ease. This societal expectation can make it difficult for mothers to acknowledge their shortcomings or struggles, leading to feelings of inadequacy.

The author suggests that there is a misconception that all mothers are always composed, healthy, and at ease in various social situations. This unrealistic standard creates a barrier for parents to express their genuine feelings, preventing them from admitting their flaws and vulnerabilities. As a result, many feel they must maintain a facade rather than seek support for their challenges.
