Full disclosure: I am not an etiquette expert. I just stumbled upon these three interesting etiquette tips and thought they were worth sharing.
Making an Introduction:
When introducing someone, you should always say their name first and their relationship to you second. That way, you spotlight the person–not their connection to you.
Wrong: “This is my husband, Jay.”
Right: “This is Jay, my husband.”
While taking a sip, you should politely look into your glass. (And not at another person, if you’re in the middle of a conversation.)
When you are finished with your meal, your knife and fork should be placed on your plate diagonally from upper left to lower right (11 to 5 if you imagine your plate as a clock face). This is a secret code to the waiter (or host) that you’re finished.
