An "excuse" is a reason or explanation given to justify a mistake, failure, or behavior. It often aims to lessen blame or responsibility for an action. People use excuses in various situations, such as missing an appointment or not completing a task on time. Excuses can be seen as a way to protect one's reputation or feelings. However, excessive use of excuses may lead to a lack of accountability. In some cases, individuals may use social norms or cultural expectations to frame their excuses, influencing how they are perceived by others.
