Keep calm and display elegance in your speech. Remember: always be witty and clever, not sarcastic and condescending. Quick wit demonstrates understanding and intelligence, and there’s no better clap back than a smart one! If you disagree, there are simple methods to avoid sounding defensive. Try saying "I believe" as opposed to "But".

If you're caught staring at someone, the recipe for the remedy is to apologise and compliment. A simple "I’m sorry, I was just admiring your beautiful necklace" will definitely change the mood. Just like the oldest trick in the book—the sales pitch compliment—people are more likely to comply with those who flatter them.

Misheard something? ‘Huh’ is not a word. Just excuse yourself and apologise for not catching what they said. "I'm sorry, I didn't catch that", is a lot more graceful than "Huh?"

Do not apologise when you don’t need to, just pardon yourself and carry on. Don’t forget to keep your composure with your body language—keep your chin up, nod your head once to acknowledge them and maintain an upright posture. Portraying welcoming body language towards threats like rudeness shows your decorum. After all, you have an entire itinerary of meeting people, don’t let the negative energy ruin your day.
