Kill Them with Kindness: Respond to rudeness with politeness. A simple, "I hope you have a great day," can disarm hostility.
Set Boundaries: Calmly assert your boundaries. For example, "I'd appreciate it if you could speak to me respectfully."
Stay Calm: Maintain your composure and avoid being drawn into an argument. Respond with, "I don't think it's productive to engage in this manner."
Ignore and Leave: Sometimes ignoring rude comments is best. Say "I prefer not to engage in this conversation" and leave.
Seek Support: If rudeness persists, reach out to a trusted friend or authority figure for guidance or intervention.
