I learned this skill from SurgeonFriend Elisabeth, whose manners are so flawless and fine.
If someone does something slightly embarrassing — drops and breaks a glass at a party, say — unless you are actively helping the cleanup, just pretend it didn’t happen. Continue on with your conversation. Not your business. This also goes for burping, mispronouncing a word, someone tripping and falling, and so on. When these things happen, you always sort of hope no one saw. It’s gracious to provide that peace of mind for others.
