Many people were raised to address others respectfully as Sir and Ma’am. Although this was polite when addressing adults as a child, it is not the best etiquette once we leave childhood behind because it can carry connotations of subservience or old age.

“As we get older, it’s much more appropriate to address someone by name,” Gottsman explains. If addressing someone by their first name seems too informal, you can address the person by their title and last name to show respect.

That’s surprising! You shouldn’t clink glasses after a toast. That’s because your host may be serving you their best glass. You don’t want to spill your drink on the beautiful table linens when you throw your cup around, and you certainly don’t want to damage or break your host’s beautiful glasses.

Of course, if someone tries to toast you, you should do so politely and not correct or ignore them. However, the preferred response to a toast is to raise your glass and nod to the other guests. Toasting is not required.

You love that photo of you at a party, but next to you is your friend taking a bite. Should you post the photo anyway? No, says Gottsman. Your friend will not appreciate having an unflattering photo of him posted online, no matter how good you look. And for safety reasons, children’s photos should never be posted online without parental permission.

When you go out with friends, you don’t always want to put the entire bill on one card. It’s perfectly acceptable to request that your orders be issued on separate bills, as long as you ask before You order. Waiting for the bill to arrive and then asking the waiter to convert them into separate bills is a hassle for the staff.

Just as you wouldn’t ask for a gift, it’s bad etiquette to try to take your food home. Tell the host to enjoy the leftovers and you can come back to pick up your serving dishes at another time. However, if the host gives you back your leftovers or insists you take some home, it’s OK to gratefully accept their offer.

This is actually not good manners, although many people think it’s chic! Gottsman calls it “affected” and explains that it makes you look like you’re trying too hard to draw attention to your supposedly good manners. The best etiquette is to hold the cup correctly and not draw attention to yourself.

A dinner party is not a drive-thru. Don’t jump in when you get your food! Wait until everyone has been served and your host takes the first bite, no matter how delicious the food smells.

You receive an invitation to a wedding, but it only has your name on it. This is a clear sign that you will not have anyone accompanying you to the event.

Even if you want to bring a friend or significant other, you should respect the host’s invitation. They may keep the guest list small or only invite married or engaged significant others. Asking to bring another companion may put the host in an awkward position if they can’t accommodate additional guests.

Always stand up when you are introduced to someone. This way you show respect to both the other person and yourself. “Always greet with your feet,” says Gottsman, who emphasizes that a greeting is not just about words, but also about body language.

Even though it’s tempting to stay seated, a little effort goes a long way toward making a good first impression.

Trust us, people getting married don’t want you to live stream their wedding on your social media. If the couple has a specific hashtag for posting pictures on social media, feel free to post under that hashtag since you’ve been invited to do so. In other cases, however, you should let the bride and groom share their special moment first and then post your party pictures.

It is a mistake of etiquette, avoid Eye contact with the people you are talking to. But it is also a mistake to too much also eye contact. Since eye contact can be intense and even a little intimate, too much of it sends too strong a message. Aim for eye contact for a few seconds at a time. Gottsman advises that you can also look between people’s eyebrows, which shows that you’re looking at them without making direct eye contact.

Suddenly, it seems like tipping is everywhere. While you shouldn’t feel pressured to tip on every transaction, it’s important to understand tipping etiquette. The customary tip used to be 15%, but with “tiplation,” 20% is now expected.

This is a fairly well-known etiquette faux pas, but it’s worth repeating. Whether someone gives you a thoughtful gift or spends their time helping you, you should always thank them appropriately. A handwritten thank you card is a simple and classy way to show your appreciation. Leaving out a thank you note can leave the gift-giver feeling unappreciated or even wondering if you even received the gift.

The popularity of social media has made it a little too easy to overshare online. It’s harder to “read the mood in the room” when you’re posting to people whose reactions you can’t see. From political rants to TMI stories, stay off your social media and both you and your followers will be happier.
