Have you ever been out to dinner with a friend, and after finishing off a leafy green salad, your friend turns to you with a wide grimace showing off their teeth and asks, “Do I have anything stuck in my teeth?” You notice a little piece of spinach stuck right in the middle of their smile. Do you tell them? They’ll be so embarrassed if you say “yes.” You decide to do the nice thing and say, “You look great!” You’re not lying. They do look great even with the green stuck in their teeth.
