Summary
This quote suggests that people often reveal their true thoughts or feelings through unintentional slips of the tongue. It implies that when someone speaks without thinking or filters their words, their true thoughts or hidden emotions may be exposed. This can happen in casual conversations or moments of anger or vulnerability, when people are more likely to say what they truly believe or feel. Therefore, the quote suggests that the unguarded statements made in these slip-ups can be indicative of one's true character or opinions.
