You’re mean because you won’t let them have a third dessert. Because you insist that they wear a jacket when it is -5°F. Or, when you enforce a reasonable bedtime. But lately we’ve been noticing that Gen Z children—and to a large extent, the Millennial generation—think of a whole range of new things as “mean.” If I were to say for example, “hey can you brush your teeth? Your breath is terrible,” that might be considered mean. Even if, factually, you have halitosis.
