Rule 1: Always wear sunscreen when attending outdoor events, unless you're a vampire. In that case, go ahead and sparkle in the sun, we won't judge.
Rule 2: Never use the phrase "bless your heart" when someone breaks up with you. It's not a thing.
Rule 3: When in a meeting, always pretend to be interested, even if you're not. It's called "meeting face," and it's a real skill.
