Canceling plans at the last moment is sometimes necessary due to health issues, mental health needs, emergencies, exhaustion, or emotional challenges. When doing so, it is best to be honest but brief about the reason, sincerely apologize, and offer to reschedule to maintain the relationship. Using polite and straightforward communication, such as saying, "I’m really sorry for the last-minute change," helps minimize hurt feelings. Expressing appreciation for the other person's understanding and suggesting an alternative meeting time shows that the friendship or relationship still matters despite the cancellation. Common reasons to cancel include not feeling well, unexpected work commitments, or family emergencies, and avoiding a pattern of last-minute cancellations is important to maintain trust and respect in relationships.
