In the quote, Mary Roach humorously expresses her disbelief when readers tell her that her books have made them laugh out loud. She points out two reasons for this skepticism: firstly, she doesn't find her own writing to be humorous enough to elicit such a reaction; and secondly, she admits to having used similar praise insincerely in the past, meaning only that a book brought her a pleasant smile rather than hearty laughter.
The deeper significance of Roach's words lies in the subjective nature of humor and how it varies from person to person. What might be hilarious for one individual may not resonate with another on the same level. Roach’s admission reflects an awareness of this variability and a willingness to acknowledge her own limitations as a writer in terms of eliciting strong emotional responses, particularly laughter. Moreover, she offers insight into the common practice of writers overstating their appreciation, perhaps out of politeness or enthusiasm, which can blur the lines between genuine praise and casual compliments.
